Abstract: Cu − SiC composites were studied by scanning electron microscopy after processes of molding and a heat treatment. After pressing, plastic deformation of copper particles and traces of destruction of silicon carbide (cracks and debris) are observed. After the solid-phase sintering, formation of a porous structure in the matrix material is noted without significant changes in the filler particles. Data on the distribution of chemical elements near the SiC − Cu interface indicate an insignificant effect of diffusion processes.
Keywords: composite, electron microscopy, copper, silicon carbide, microstructure, pores.
