Comparative analysis of graphite inclusions in chrome cast iron structure

Abstract

The paper presents the results of a quantitative metallographic analysis of graphite inclusions in the structure of chrome cast irons including cast iron of the Nihard class, as well as after treatment with titanium carbide. The ThixometPro software was used for the analysis. The shape, size, perimeter, distribution density of graphite inclusions, as well as the area occupied by the structural components and their dispersion were evaluated. It is shown that the introduction of titanium carbide has a favorable effect on the pattern of graphite inclusions and some parameters of the structure in general.
