Abstract

The object of investigations was two-phase steel having the austenitic structure with ferrite precipitates (volume fraction about I 0% ). The material was subjected to cold rolling up to about 85% of deformation and subsequently annealed within the temperature range 750°C+l000°C. X-ray investigations included the phase analysis, measurements of pole figures and calculations of the orientation distribution functions (ODF's) for both component phases. The textures of austenite and ferrite after the final rolling reduction and successive stages of annealing were analysed within the centre and surface layers of the sheets. Examination of the austenite recrystallization texture included additionally the analysis of orientation fibres and transformations of the experimental and ideal ODF's. From the texture analysis it results that the mechanisms controlling the development of the austenite recrystallization texture is the selective growth of twins. Texture simulations indicate that austenite rolling texture can be transformed into the recrystallization texture according to twin relation, i.e. by rotation through an angle of (2n - I) x 60° about < I 11 >poles. A certain contribution of the oriented growth into the texture formation was also found. In that case relation between the recrystallization and deformation textures may be described by rotation 30°+40°/<111>. In both cases a variant selection of the rotation axis takes place. Based on the texture examination and the phase analysis it is additionally assumed that the (a ➔y) phase transformation may exert some effect on the recrystallization textures of both component phases

Abstract

The stored energy e, due to plastic deformation is defined as the change in internal energy measured at stress free state of material, and it characterises the cold-worked state. Both cold-worked state and the stored energy at each instant of deformation depend on the deformation history. Therefore, the instantaneous rate de,f dwP of energy storage seems to be an appropriate measure of the energy conversion process (wP is the work of plastic deformation). The rate of energy storage is important characteristic of the whole energy storage processes. It is a macroscopic quantity that is influenced by many microscopic mechanisms. Each of them is described by the separate internal paramenter H;. In mathematical description, the stored energy is a function of H,, H2, H3 •.• , H,,. Since there exist couplings between different mechanisms the function can not be, in general, written in the from: Le'..° (H;). The similar remark concerns also the energy storage rate. i= I The present paper is devoted an answer if it is possible to distinguish the influence of the change in given internal parameter on the rate of energy storage. In order to find the answer the theoretical analysis of energy storage rate on the basis of phenomenological thermodynamics of plastic deformation was done. The theoretical description of the experimental method od stored energy determination is presented. The results of the analysis have been used to support the additive partitioning of the resultant rate of the energy stored and to show experiment which allows distinguishing the particular components. Each component represents the specific microscopic mechanism. The analysis of preliminary experimental data arrived at the conclusion that in the initial stage of plastic deformation of polycrystalline metal at least two components of the energy storage rate exist. One of them is associated with the rise of dislocation density, and another one is related to the internal stress field due to elastic accommodation of incompatible strains in the vicinity of grain boundaries.

Abstract

The existing methods of analysis of drawing with a floating plug stated the most favourable angle differences between the drawing die and the plug. In the paper the theoretical analysis is made enabling achieving the possibly minimal diameter reduction at the stated wall thickness reduction. There is discussed tool geometry and a state of stress, which enable stable guidance of the process. The experimental studies with drawing of OF-Cu copper and CuZn37 brass tubes confirmed the results of theoretical consideration.

Abstract

Recently, new methods for utilization of converter slag have been sought. Slag processing by reduction in an electric arc furnace is one of such methods. However, the state of the relevant investigations is rather poor. This was the reason for carrying out study aimed at developing a new technology of the process under industrial conditions. The study presented allows chemical composition of non-metallic and metal phases and the reduction level of the converter slag components during process run in an electric arc furnace to be determined.

Abstract

The paper presents the results of SrSO4 reduction and SrS oxidation with the use of gaseous mixture (CO+CO2) in 1073-1373 K temperature range. On the base of an assumed equation describing the process in the wide range of reaction stage the dependence of constant reaction rates on CO concentration in the gaseous phase. The value of reaction activation energy and its change depending on the composition of the gaseous phase (CO+CO2) has been defined. The boundary value CO concentration in the gaseous phase, above which reductions, and below which oxidation of SrS take place, has been defined.

Abstract

Przegląd literaturowy stosowanych na świecie technologii do przerobu stopów Zn-Ag-Pb wskazuje, że najefektywniejszą technologią jest metoda destylacji próżniowej, oparta na zjawiskach parowania lotnych składników z kąpieli metalicznej. W procesie odparowania składników z ciekłych stopów, w warunkach obniżonego ciśnienia, podstawowe znaczenie odgrywają zjawiska transportu masy. Badania procesu parowania w próżni wykazują, że jego szybkość może być zwiększona nie tylko przez obniżenie ciśnienia czy wzrost temperatury procesu, lecz także przez zmianę warunków hydrodynamicznych w układzie. Można także przypuszczać, że w zależności od rodzaju stopu kontrola kinetyczna omawianego procesu jest znacznie zróżnicowana. Wykazanie, który z tych czynników najistotniej wpływa na kinetykę procesu parowania, wymaga określenia etapu kontrolującego proces, a także określenia wpływu tych czynników na zmianę jego kontroli. W ramach pracy przeprowadzono badania próżniowego oddestylowania cynku ze stopów Zn-Ag-Pb w zakresie ciśnień od I do 1000 Pa i temperatur od 823 do 898 K. Badania przeprowadzono dla stopu o składzie chemicznym: 50,0% Ag, 35,0% Pb i 15,0% Zn. Podstawowym urządzeniem wykorzystywanym w badaniach był agregat próżniowy składający się z głowicy roboczej, pieca indukcyjnego PIS O I TR i układu pomp próżniowych SP2000 PA. Po każdym doświadczeniu określano wielkość ubytku masy próbki oraz analizowano skład chemiczny stopu oznaczając zawartość: cynku, srebra i ołowiu metodą atomowej spektrometrii absorpcyjnej (AAS) z zastosowaniem spektrometru firmy Perkin-Elmer model 603. Na podstawie analizy uzyskanych wartości podstawowych parametrów kinetycznych: gęstości strumienia masy oraz współczynnika przenikania masy dla zakresu ciśnień od IO do 20 Pa obserwuje się silną zależność tych wielkości od ciśnienia panującego w układzie pomiarowym. Oznacza to, że w tym zakresie ciśnień następuje zmiana kontroli procesu i opory w fazie gazowej nakładają się na opory w fazie ciekłej. Można więc przyjąć, że w obszarze ciśnień od IO do 20 Pa mamy do czynienia z mieszaną kontrolą procesu. W zakresie ciśnień powyżej 20 Pa można natomiast przyjąć, że proces zachodzi w obszarze dyfuzyjnym i jest kontrolowany oporami w fazie gazowej. Szybkość procesu odcynkowania stopów Zn-Ag-Pb wzrasta silniej w miarę obniżania ciśnienia niż przy wzroście temperatury. W zakresie ciśnień poniżej IO Pa, wartości pozornej energii aktywacji procesu zbliżone są do wartości energii aktywacji dyfuzji cynku w ciekłym srebrze. Stanowi to potwierdzenie faktu, że w tym zakresie ciśnień proces destylacji cynku kontrolowany jest głównie transportem masy w fazie ciekłej.

Abstract

Constituent binary subsystems Co-Cu, Co-Si and Cu-Si were described briefly, and their calculated phase diagrams were presented and invariant reactions of the liquid phase, as well. Thermodynamic parameters for Co-Si and Cu-Si systems were taken from the former own assessments and coefficients for binary system Co-Cu were accepted from the one of the most recent literature evaluations. Tdb file was then set up by means of binary formalism. Equilibrium calculations resulted in the parameters of all invariant reactions with liquid phase involved, and the Schei l reaction scheme was constructed as well. Graphical representation of the calculated liquidus surface was shown as the projection onto the G i b b s triangle plane.

Abstract

Brief review on history and development of OTA as thermal analysis method; with special aspect to the application of quantitative thermodynaimc analysis for binary metal systems, are presented in this paper. Importance of the calibration constat determination is pointed out, as well as its changeable value depending on composition of the investigated system. Results obtained using OTA method in termodynamic analysis of some binary systems are also given and compared with data measured by other experimental techniques (calorimetry, EMF measurements) or calculated by thermodynamic predicting methods. Good agreement reached between these results enables to the correctness of application of quantitative OTA.

4. Review and proofread process

4.1. Peer review process All submitted manuscripts undergo review by renowned specialists appointed by the Editor-in-Chief and members of the Editorial Board. Reviewers receive guidance to help them perform the review, and submit written opinion on the manuscript together with recommendation to accept as is, or reject, or accept after revision. In the latter case i.e. when revision is requested, the authors are obliged to respond to Editor and Reviewers’ comments in detail and make revisions to the manuscript. A rebuttal to Reviewers’ comments can also be sent via the Editorial System in writing. Decision to reject the article is taken by the Editorial Board with the final decision belonging to the Editor, who may appoint another reviewer if necessary. Reviewers remain anonymous to Authors and their identity cannot be revealed by the Editorial Office.

In a separate file, the authors are requested to suggest names and contact details (affiliations and valid e-mail addresses) of at least three experts who could serve as reviewers.

Brief explanation (2-3 sentence-long) why each person is suitable as a reviewer should also be provided. The suggested reviewers cannot be from the same country as affiliation of the corresponding author. The decision to appoint a reviewer belongs solely to the editor.

4.2. Revised manuscript submission

When revision of a manuscript is requested, Authors should return the revised version of their manuscript as soon as possible. Prompt action may ensure fast publication if a paper is finally accepted for publication in Arch. Metall. Mater. If it is the first revision of an article Authors are requested to return their revised manuscript within 7 days.

If it is the second revision Authors are requested to return their revised manuscript within 1 day.

4.3. Final proofreading

Authors will receive a pdf file with the edited version of their manuscript for final proofreading. This is the last opportunity to view an article before its publication on the journal web site. No changes or modifications can be introduced once it is published. Thus authors are requested to check their proof pages carefully against manuscript within 3 working days and prepare a separate document containing all changes that should be introduced. Authors are sometimes asked to provide additional comments and explanations in response to remarks and queries from the language or technical editors.
