Method for Evaluation and Visualization of the Microstructure Materials Heterogeneity

Abstract—Methods of stereometric metallography of the microstructure of steels and alloys have been considered. In addition to the accepted results of the analysis, parameters of the sample range and the unit continuous second-phase length and analysis of changes in the sequential volume of the second phase have been proposed, and a method for visualization of the results in the form of polar diagrams has been developed and presented. As an example, studies were performed on grade 40 carbon steel microsections without etching. Defect-free samples and samples with dot and line inclusions were considered. The use of the methods under consideration makes it possible to increase the accuracy of determining the directions of deformation impacts and to detect the presence of inclusions and evaluate their size and volume in alloys from an analyzed image.
