Abstract
Stereological description of dispersed microstructure is not an easy task
and remains the subject of continuous research. In its practical
aspect, a correct stereological description of this type of structure is
essential for the analysis of processes of coagulation
and spheroidisation, or for studies of relationships between structure and
properties. One of the most frequently used methods for an
estimation of the density Nv and size distribution of particles is the Scheil
- Schwartz – Saltykov method. In this article, the authors present
selected methods for quantitative assessment of ductile iron microstructure,
i.e. the Scheil - Schwartz – Saltykov method, which allows
a quantitative description of three-dimensional sets of solids using
measurements and counts performed on two-dimensional cross-sections
of these sets (microsections) and quantitative description of
three-dimensional sets of solids by X-ray computed microtomography, which
is an interesting alternative for structural studies compared to traditional
methods of microstructure imaging since, as a result, the analysis
provides a three-dimensional imaging of microstructures examined.
