Abstract
Methods of stereometric metallography of microstructure of steels and alloys have been considered. In addition to the accepted analysis results the parameters of the sample span, the single continuous length of the second phase, the analysis of changing in the sequential volume of the second phase are proposed. A method for visualizing the results in the form of polar diagrams was developed and presented. As an example, the studies were carried out on carbon steel 40 micro-grinders without etching. Defect-free samples and samples with dot and line inclusions were considered. The application results of the considered methods make possible to increase the accuracy of determining the directions of deformation effects, to determine the presence, size and volume of inclusions in alloys on the basis of an analyzed image.
