Microstructural Analysis of Granular Metal-Ceramic Composite Materials of Matrix Type

Abstract

The cluster structure of microphotographs of the metal-ceramic composite materials surface samples has been analyzed. Cluster analysis has been performed with the help of a self-organizing feature map in a four-dimensional feature space, built from textural visualizations of a microphotograph. As a result of our studies, two types of cluster structure elements were found: small-scale and large-scale clusters. The assumption has been made that two main features of the deformation graph can be associated with the destruction of the cluster elements of both kinds. As a result of multifractal analysis, it was found out that the difference in technology does not significantly affect the multifractal spectra, but it proves to be significant for multifractal dimensions.
