The aim of the article was to determine the impact of crushed condition (work hardening) on the effectiveness of the vibratory machining. The vibratory machining processing was carried out in two steps. The first step consisted of mechanical abrasion and remove oxides from the surface of the workpieces with abrasive media. While in the second step, smoothing - polishing with metal media was performed. Vibratory polishing also strengthened the treated surfaces. The test results were compared for samples in the crushed state (work hardening, plastic processing) and samples subjected to recrystallization annealing heat treatment. Mass losses, changes in the geometric structure of the surface and changes in the hardness of the machining surfaces were analyzed. Samples subjected to recrystallization, as compared to the samples in the state after work hardening-plastic working, are characterized by a slightly higher arithmetic mean surface roughness and lower surface hardness than for analogous processes for samples not subjected to heat treatment. Heat treatment of annealing allows to remove the effects of crushing and thus it is possible to obtain larger mass losses. Smaller burrs dimensions were obtained for samples after the heat treatment – annealing than after work hardening.

Abstrakt

The aim of the following work was to determine the possibility of using barley malt as a binder in moulding sands technology. The moulding sands prepared on the basis of three kinds of sands, i.e. quartz, olivine and chromite sands were analyzed. In order to determine the properties of moulding sands, typical determinations were made, i.e. moisture content, flowability, permeability, strength properties and abrasion wear. The obtained results indicate that it is possible to use barley malt as an independent binder for masses made of quartz, olivine and chromite sands.

Abstrakt

Binder jetting (BJ) sand printing is a 3D printing process in which a sand mould or sand core is produced from an STL file. A single layer of a sand matrix consisting of one or more grains in height of sand is applied to a worktable, and then a liquid resin or binder is applied to bond the grains together. This process is repeated until the final result matches the CAD model. The sand matrix is the main component of ceramic cores and moulds. The present study aims to demonstrate the influence of the matrix used on the properties of the resulting moulding sand. Three types of sand matrices were selected for the study. The first was a quartz matrix for 3D printing with binder jetting; this is characterised by a sharp geometry that allows for proper layering during printing. Ordinary quartz sand was also used for the study; this type of sand is usually used for the production of sand cores in the hotbox process, among other things. The shape of this sand is irregular. The last matrix to be tested was Cerabeads sand; this was selected because its spherical geometry clearly distinguishes it from the other two matrices. The matrices were analysed for their grain sizes. Scanning electron microscope images were also taken to compare the geometries and chemical compositions of the respective matrices. In presented research utilises a sand matrix for the production of self-curing compounds with furan resin dedicated for binder jetting 3D printing. The moulding masses were produced in a laboratory circulation mixer. The laboratory moulds were produced with wooden core boxes and pre-compacted by vibration. The samples from the matrix for the 3D printing were produced using the binder jetting method. The samples were produced to determine the flexural strength, tensile strength, gas permeability, hot distortion, and apparent density. It was not possible to carry out tests for the Cerabeads sand, as the obtained moulds were too brittle to perform adequate tests. Tests with the other matrices have shown that the shape and size of the matrix affect the apparent density and gas permeability.

Composite Multimetal Stahl 1018 has been used in the process of preserving worn surfaces of materials operating in extremely difficult conditions. This work presents the results of simulation of the mechanical properties of steel samples in contact with the MM "Stahl 1018" composite. Tests were carried out for various models with with one- and two-sided contact sample models with the composite. Theoretical tests were conducted in the "SolidWorks 2019" environment. It was found that the maximum strength of the specimen layer made of MM "Stahl 1018" material, which closely adheres to the surfaces of steel bases on both sides (444 MPa) is higher than that of the material layer in one-sided contact (358 MPa), for specimens with a height of 4.5 mm and at 80 °C. Simulations also revealed a significant increase in the maximum stress in the composite MM "Stahl 1018" for specimens in the so-called free state from 285 MPa to 358 MPa with the increasing temperature from 20 °C to 80 °C, for specimens 4.5 mm high.

Słowa kluczowe: Lean Management Ishikawa diagram Pareto-Lorenz chart Casting defects Engine pistons

Pobierz PDF Pobierz RIS Pobierz Bibtex

Abstrakt

The article presents the most significant material defects found in pistons for internal combustion engines, along with a graphical method of categorization using a Pareto-Lorenz chart. For the top three defects (constituting approximately 80% of all issues), a slightly different Ishikawa chart was employed to identify the causes behind their occurrence. Remedial actions were proposed, to be implemented primarily within the interoperative quality control of piston casting. It was concluded that it is crucial to prevent the excessive iron content in the alloy used for alfin inserts (AS9 alloy), particularly for cast iron ring carriers. The research was conducted in collaboration with Federal-Mogul company in Gorzyce (F-MG), one of the largest piston foundries in Poland.

Abstrakt

There is growing interest in developing more advanced materials, as conventional materials are unable to meet the demands of the automotive, aerospace, and military industries. To meet the needs of these sectors, the use of advanced materials with superior properties, such as metal matrix composites, is essential. This paper discusses the evaluation of microstructural and mechanical properties of conventional eutectic EN AC-AlSi12CuNiMg aluminum alloy (AlSi12) and advanced composite based on EN AC-AlSi12CuNiMg alloy matrix with 10 wt% SiC particle reinforcement (AlSi12/10SiCp). The microstructure of these materials was investigated with the help of metallographic techniques, specifically using a light microscope (LM) and a scanning electron microscope (SEM). The results of the microstructural analysis show that the SiC particles are uniformly distributed in the matrix. The results of the mechanical tests indicate that the tensile properties and hardness of the AlSi12/10SiCp composite are significantly higher than those of the unreinforced eutectic alloy. For AlSi12/10SiCp composite, the tensile strength is 21% higher, the yield strength is 16% higher, the modulus of elasticity is 20% higher, and the hardness is 11% higher than unreinforced matrix alloy. However, the unreinforced AlSi12 alloy has a percentage elongation that is 16% higher than the composite material. This shows that the AlSi12/10SiCp composite has a lower ductility than the unreinforced AlSi12 alloy. The tensile specimens of the tested composite broke apart in a brittle manner with no discernible neck development, in contrast to the matrix specimens, which broke apart in a ductile manner with very little discernible neck formation.

In the paper, the results of a numerical analysis of KCl and KF particles present in liquid aluminium assimilation to the slag are presented. The authors analysed particle movement in the slag model, which is based on buoyant, capillary, viscosity, Newton and repulsion forces, interfacial tensions at the interface of phases and surface energy during the particle movement through phases boundary. On the basis of the mathematical model, a computer programme was written to make simulations under different conditions. The results of particle position in the slag are presented for different particle radiuses: 1, 5, 10, 20 μm, and constant viscosity of the slag including velocity evolution of the velocity. Another approach was used to indicate the influence of slag viscosity on particle and slag penetration depth. During computations, selected viscosities of slag of 0.0012, 0.0015, 0.0018 [kg/m·s] were taken into account. Different comparisons were made for the chosen particle sizes. Each examination takes into account the impact of the particle type. The results clearly show that for larger particles the penetration depth is greater and viscosity of the slag has an impact on the velocity evolution during assimilation process.

To improve the mechanical properties of casting aluminum-copper alloy, the mixed rare earth (RE) was added to ZL206 and its properties and the enhanced mechanism of alloy were researched. The results showed that the strength and hardness of the composite were improved by 10.2% and 6.2%, respectively. After adding mixed RE, which was led by the heterogeneous enrichment area blocking the growth of the α-Al phase and making grain refinement during the solidification process. The simulation results of RE surface adsorption models by first principles also showed that the elastic constant calculation improved the bulk modulus, shear modulus, and Young's modulus of the material. The addition of mixed RE enhances the strength and hardness, although it adversely affects toughness and reduces the machining index. Also, the work function decreased, and the Fermi level increased, reflecting that the electron locality on each band was strong and the bonding state of the alloy system was covalent, which showed that the corrosion resistance was enhanced after adding mixed RE. It provides a new method for the mechanism of RE-modified aluminum-copper alloys and expands the direction of cast aluminum-copper alloy modification.

Abstrakt

The present study evaluates the microstructural features, mechanical properties, and wear characteristics of the newly developed hybrid composite of A356/ZrO₂/Al₂O₃/SiC produced by compo-casting at 605±5 °C, 600 rpm for 15 minutes with less than 30% solid fraction in which Bi and Sn were added separately to the matrix before introducing reinforcements. FESEM micrographs and corresponding EDS illustrated the successful incorporation of particles in the matrix. Fine particles of ZrO2 were observed close to the coarse Al₂O₃, and SiC particles, along with Bi and Sn elements, were detected at the eutectic evolution region. The A356+Bi/Al₂O₃+ZrO₂+SiC hybrid composite exhibited the lowest specific wear rate (1.642 ×10^-7cm³/Nm) and friction coefficient (0.31) under applied loads of 5, 10, and 20 N, in line with the highest hardness (73.4 HBN). Analysis of the worn surfaces revealed that the wear mechanism is mostly adhesive in all synthesized composites, which changed to the combination of adhesive and abrasive mode in the case containing Bi and SiC. Inserting Bi not only leads to the refinement of eutectic Si but also enhances the adhesion between the matrix/particles and improves lubricity. This, in turn, reduces the wear rate and coefficient of friction, ultimately improving the performance of the hybrid composite.

The publication presents a new shooting technique with reduced pressure in venting system for manufacturing foundry cores using inorganic sand mixture with Cordis binder. Traditional technologies for producing casting cores using blowing methods, despite their undeniable advantages, including the ability to produce cores in series, also come with some disadvantages. The primary drawbacks of the process involve uneven compaction structure of the cores, with denser areas primarily located under the blow holes, and under-shooting defects, which often occur in regions away from the blow hole or in increased core cross-sectional areas. In an effort to improve core quality, a concept was developed that involves incorporating a reduced pressure in the core box venting system to support the basic overpressure process. The solutions proposed in the publication with a vacuum method of filling the cavities of multi-chamber core boxes solve a number of technical problems occurring in conventional blowing technologies. It eliminates difficulties associated with evacuating the sand from the chamber to the shooting head and into technological cavity and increases the uniform distribution and initial degree of compacting of grains in the cavity. The additive role of this “underpressure” support is to enhance corebox venting by eliminating 'air cushions' in crevices and structural elements that obstruct the flow of evacuated air. The publication presents the results of studies on core manufacturing using blowing methods conducted in three variants: classic overpressure, utilizing the core box filling phenomenon by reducing pressure, and an integrated approach combining both these methods.

Abstrakt

The article discusses the growing importance of decarbonization of production systems in the foundry industry as a response to climate challenges and increasing requirements for sustainable development. The process of reducing greenhouse gas emissions in foundry production is caused by a number of reasons. Decarbonization of the foundry industry refers to actions aimed at reducing greenhouse gas emissions, especially carbon dioxide (CO₂). Reducing carbon dioxide emissions is increasingly being considered as a key element of the strategy of both small and large foundries around the world. Foundry is one of the industries that generates significant amounts of carbon dioxide emissions due to the energy consumption in the process of melting and forming metals. There is virtually no manufacturing industry that does not use elements cast from iron, steel or non-ferrous metals, ranging from elements made of aluminum to zinc. The article presents various decarbonization strategies available to foundries, such as: the use of renewable energy, the use of more efficient melting technologies, or the implementation of low-energy technologies throughout the production process. Application examples from different parts of the world illustrate how these strategies are already being put into practice, as well as the potential obstacles and challenges to full decarbonization.

Abstrakt

As an alloying element in steel, manganese can considerably enhance the mechanical properties of structural steel. However, the Mn volatilisation loss in vacuum melting is severe because of the high saturated vapour pressure, resulting in an unstable Mn yield and Mn content fluctuation. Therefore, a systematic study of the volatilisation behaviour of Mn in vacuum melting is required to obtain a suitable Mn control process to achieve precise control of Mn composition, thereby providing a theoretical basis for industrial melting of high-Mn steel. In order to explore the Mn volatilization behavior, the volatilization thermodynamics and volatilisation rate of Mn, as well as the influence factors are discussed in this study. The results shows that Mn is extremely volatilised into the vapour phase under vacuum, the equilibrium partial pressure is closely related to Mn content and temperature. With an increase in the Mn content, a higher C content has a more obvious inhibitory effect on the equilibrium partial pressure of Mn. The maximum theoretical volatilisation rate of Mn shows a linear upward trend with an increase in Mn content. However, a higher C content has a more obvious effect on the reduction of the maximum theoretical volatilisation rate with the increase of Mn content. This study provides an improved understanding of Mn volatilisation behaviour as well as a theoretical foundation for consistent Mn yield control during the vacuum melting process of high-Mn steel.

Abstrakt

Sodium silicate, known for its low cost and non-toxicity, has been considered as a promising option for green foundry in terms of mould sands. However, the utilization of used sodium silicate sands has posed significant challenges. To address the issues of high energy consumption and secondary pollution associated with wet and dry regeneration of sodium silicate used sands, this paper proposes a novel unattended biological regeneration system. The system involves culturing diatoms in an incubator with a solution of sodium silicate used sands. The incubator is equipped with built-in sensors that continuously monitor temperature, illuminance, pH, and water level. The monitoring data is transmitted in real-time to the Yeelink Internet of Things platform via the controller using the TCP/IP protocol. By logging onto the corresponding web page, the experimenter can remotely observe the monitoring data. The results of the experiment indicate that diatoms bloomed five times, and the water pH decreased from 10.2 to 8.2 after 40 days of cultivation. Additionally, the film removal rate of the used sands reached 90.26%.

The paper presents the results of the analysis of cooling curves of cast iron with approximately eutectic composition rasterized at different rates of cooling and ingot crystallization. The test samples were in the form of rods with a diameter of 30,0.mm and a coagulation modulus M = 0.75 cm. They were cast in a sand mould made of furan mass placed on a chill in the form of a cast-iron plate, with which one of the front surfaces of the rod casting was in contact. In this way, a differentiated cooling rate along the rod was achieved. At selected distances from the chiller (5, 15, 25, 25 and 45 mm) thermocouple moulds were placed in the cavity to record the cooling curves used in thermal (AT) and derivation (ATD) analysis. The solidification time of the ingot in the part farthest from the chiller was about 200s, which corresponds to the solidification time in the test cup AT. An analysis of the recorded cooling curves was performed in order to determine the values of characteristic points on the AT curve (Tsol. Tliq, ΔTrecal., τclot, etc.). Relationships between cooling time and rate and characteristic points on AT and ATD curves were developed. For example, Tsol min changes in the range of 1115 - 1145 for the range of cast iron solidification times in the selected ingot zone from ~ 70 to ~ 200 s, which corresponds to the process speed from 0.0047 to 0.014 [1/s]. The work also includes an analysis of other characteristic points on the AT and ATD curves as functions of the solidification rate of cast iron of the same composition.

Abstrakt

A method for fabrication of a composite layer on the surface of a steel casting using coating containing TiC substrates was presented. The reaction of the synthesis of the ceramic phase was based on the SHS method (Self-propagating High-temperature Synthesis) and was triggered by the heat of molten steel. High hardness titanium carbide ceramic phases were obtained, which strengthened the base material improving its performance properties presented in this article. Microstructural examinations carried out by light microscopy (LM) on the in-situ produced composite layers showed that the layers were the products of reaction of the TiC synthesis – the phenomenon called “fragmentation” by the authors of study. The examinations carried out by scanning electron microscopy (SEM) have revealed the presence of spheroidal precipitated and free of impurities. The presence of titanium carbide was twofold increase in hardness in the area of the composite layer as compared to the base alloy which was carbon cast steel.

This research investigates the microstructural evolution and mechanical properties of LM25 (Al-Si-Mg) alloy and Cr-modified LM25-Cr (Al-Si-Mg-Cr) alloy. Microstructural analysis reveals distinctive ε-Si phase morphologies, with Cr addition refining dendritic structures and reducing secondary dendrite arm spacing in the as-cast condition. Cr modification results in smaller-sized grains and a modified ε-Si phase, enhancing nucleation sites and reducing ε-Si size. Microhardness studies demonstrate significant increases in hardness for both alloys after solutionising and aging treatments. Cr-enriched alloy exhibits superior hardness due to solid solution strengthening, and prolonged aging further influences ε-Si particle size and distribution. The concurrent rise in microhardness, attributed to refined dendritic structures and unique ε-Si morphology, underscores the crucial role of Cr modification in tailoring the mechanical properties of aluminium alloys for specific applications.

The article describes the simulation of the casting of the low-melting material stearin into a mold, which serves as a real simulation basis for monitoring the displacement during the solidification of steel ingots. The physical properties and occurrence of shrinkage are comparable for both liquid stearin and molten steel. In this way, it is possible to easily monitor the solidification of ingots after casting, while the entire simulation takes place at low temperatures, which is experimentally simpler and more practical than trial casting steel at high temperatures. The process is convenient, simple, fast and cheap. The essence is therefore the application of a new perspective on the mentioned process and its transfer into foundry practice. The temperature drop in the entire volume of the sample was monitored from filling the mold to cooling to ambient temperature and the formation of shrinkage, which was monitored and evaluated in the internal body of the ingot. The tests confirmed the suitability of selected material for this method of experimental work because they were able to capture the real behavior of the cast steel in the mold. The method proves to be suitable for industrial applications where similar multidimensional castings are produced.

The work presents monitoring of the corrosion rate for pure magnesium and the binary magnesium alloy Mg72Zn28. Alloying elements with a purity of 99.9% were used. The melting was performed under the protection of inert gas - argon in an induction furnace. The liquid alloy was poured into a copper mold. In order to make amorphous ribbons, the obtained samples in the form of rods were re-melted on a melt spinner machine. The next step was to perform corrosion tests in Ringer's solution. Corrosion tests were carried out at a temperature of 37°C and pH 7.2. The purpose of using Ringer's solution was to recreate the conditions for the body fluids of the human body. The use of the following research methods, such as: OCP (open circuit potential), LSV (linear sweep voltammetry) and EIS (electrochemical impedance spectroscopy), was aimed at determining the corrosion resistance of the tested materials. Tests carried out in Ringer's solution showed that pure magnesium has significantly worse corrosion resistance than the binary Mg72Zn28 alloy. The conducted research also confirmed that the cathodic reaction takes place faster on the surface of amorphous ribbons. It was also confirmed that for both crystalline materials there is diffusion of chloride ions through the corrosion product layer. SEM-EDS tests were performed on the surface of an amorphous ribbon of the Mg72Zn28 alloy after corrosion in Ringer's solution.

20 Usage of the Cast Iron Cylindrical Liner in an Automobile Engine Block

Pobierz PDF Pobierz RIS Pobierz Bibtex

Abstrakt

This study addresses the issues related to the quality of the connection between cast iron liners and inserts in a pressure die-cast automotive engine block, along with the macro and micro wear of the cylinder bearing surface. it was found that the commonly used HPDC high-pressure casting technology of Al-Si alloy engine blocks with cast iron liners, in which the cylinder liner is then recreated, does not ensure their metallic connection. The micro-gap created there becomes thicker as the engine is used, which worsens the conditions for heat dissipation from the sleeve to the block. Locally, on the surface of the cylinder bearing surface, reductions in honing effects and longitudinal cracks were observed. The presented literature mechanism of micro wear of the cylinder bearing surface, dependent on the morphology of graphite segregations, was confirmed. The mechanism of creating micro-breaks in the area of phosphoric eutectic and graphite precipitation occurrence was presented, initiated by the formation of microcracks in the eutectic and delaminations at the eutectic-matrix boundary.

Retractions of the articles: the Editor in Chief will consider retracting a publication if:
- there are clear evidences that the findings are unreliable, either as a result of misconduct (e.g. data fabrication) or honest error (e.g. miscalculation or experimental error)
- the findings have previously been published elsewhere without proper cross-referencing, permission or justification (cases of redundant publication)
- it constitutes plagiarism or reports unethical research.
Notice of the retraction will be linked to the retracted article (by including the title and authors in the retraction heading), clearly identifies the retracted article and state who is retracting the article. Retraction notices should always mention the reason(s) for retraction to distinguish honest error from misconduct.
Retracted articles will not be removed from printed copies of the journal nor from electronic archives but their retracted status will be indicated as clearly as possible.

Duties of Authors
1. Reporting standards: Authors of original research should present an accurate account of the work performed as well as an objective discussion of its significance. Underlying data should be represented accurately in the paper. The paper should contain sufficient details and references to permit others to replicate the work. The fabrication of results and making of fraudulent or inaccurate statements constitute unethical behavior and will cause rejection or retraction of a manuscript or a published article.
2. Originality and plagiarism: Authors should ensure that they have written entirely original works, and if the authors have used the work and/or words of others they need to be cited or quoted. Plagiarism and fraudulent data is not acceptable.
3. Data access retention: Authors may be asked to provide the raw data for editorial review, should be prepared to provide public access to such data, and should be prepared to retain such data for a reasonable time after publication of their paper.
4. Multiple or concurrent publication: Authors should not in general publish a manuscript describing essentially the same research in more than one journal. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable.
5. Authorship of the manuscript: Authorship should be limited to those who have made a significant contribution to the conception, design, execution, or interpretation of the report study. All those who have made contributions should be listed as co-authors. The corresponding author should ensure that all appropriate co-authors and no inappropriate co-authors are included in the paper, and that all co-authors have seen and approved the final version of the paper and have agreed to its submission for publication.
6. Acknowledgement of sources: The proper acknowledgment of the work of others must always be given. The authors should cite publications that have been influential in determining the scope of the reported work.
7. Fundamental errors in published works: When the author discovers a significant error or inaccuracy in his/her own published work, it is the author’s obligation to promptly notify the journal editor or publisher and cooperate with the editor to retract or correct the paper.

Duties of Reviewers
1. Contribution to editorial decisions: Peer reviews assist the editor in making editorial decisions and may also help authors to improve their manuscript.
2. Promptness: Any selected reviewer who feels unqualified to review the research reported in a manuscript or knows that its timely review will be impossible should notify the editor and excuse himself/herself from the review process.
3. Confidentiality: All manuscript received for review must be treated as confidential documents. They must not be shown to or discussed with others except those authorized by the editor.
4. Standards of objectivity: Reviews should be conducted objectively. Personal criticism of the author is inappropriate. Reviewers should express their views clearly with appropriate supporting arguments.
5. Acknowledgement of sources: Reviewers should identify the relevant published work that has not been cited by authors. Any substantial similarity or overlap between the manuscript under consideration and any other published paper should be reported to the editor.
6. Disclosure and conflict of Interest: Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should not consider evaluating manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relations with any of the authors, companies, or institutions involved in writing a paper.

Procedura recenzowania

Review Procedure

The Review Procedure for articles submitted to the Archives of Foundry Engineering agrees with the recommendations of the Ministry of Science and Higher Education published in a booklet: ‘Dobre praktyki w procedurach recenzyjnych w nauce’ (MNiSW, Dobre praktyki w procedurach recenzyjnych w nauce, Warszawa 2011).

Papers submitted to the Editorial System are primarily screened by editors with respect to scope, formal issues and used template. Texts with obvious errors (formatting other than requested, missing references, evidently low scientific quality) will be rejected at this stage or will be sent for the adjustments.

Once verified each article is checked by the anti-plagiarism system Cross Check powered by iThenticate®. After the positive response, the article is moved into: Initially verified manuscripts. When the similarity level is too high, the article will be rejected. There is no strict rule (i.e., percentage of the similarity), and it is always subject to the Editor’s decision.
Initially verified manuscripts are then sent to at least four independent referees outside the author’s institution and at least two of them outside of Poland, who:

have no conflict of interests with the author,
are not in professional relationships with the author,
are competent in a given discipline and have at least a doctorate degree and respective
scientific achievements,
have a good reputation as reviewers.

The review form is available online at the Journal’s Editorial System and contains the following sections:

1. Article number and title in the Editorial System

2. The statement of the Reviewer (to choose the right options):

I declare that I have not guessed the identity of the Author. I declare that I have guessed the identity of the Author, but there is no conflict of interest

3. Detailed evaluation of the manuscript against other researches published to this point:

Do you think that the paper title corresponds with its contents?
Yes No
Do you think that the abstract expresses the paper contents well?
Yes No
Are the results or methods presented in the paper novel?
Yes No
Do the author(s) state clearly what they have achieved?
Yes No
Do you find the terminology employed proper?
Yes No
Do you find the bibliography representative and up-to-date?
Yes No
Do you find all necessary illustrations and tables?
Yes No
Do you think that the paper will be of interest to the journal readers?
Yes No

4. Reviewer conclusion

Accept without changes
Accept after changes suggested by reviewer.
Rate manuscript once again after major changes and another review
Reject

5. Information for Editors (not visible for authors).

6. Information for Authors
