Visualization of the Phase Volume Distribution in Alloys

The method of obtaining the volume distribution of phases in structural materials is considered. The technique is based on the layer-by-layer grinding of metallographic samples with photo fixation of microstructure images and the subsequent computer processing of these images. An example of using the developed methodology to study the features of the volumetric distribution of graphite inclusions in high-strength cast irons is presented. The classification of graphite inclusions depending on the shape, size and distribution features is given. The study of the features of the distribution of graphite inclusions led to the conclusion about the patterns and mechanisms of formation graphite phase in cast iron.
