Study of structure of copper-based composite materials during the spark plasma sintering

Abstract

This paper is devoted to the study of copper-based composite materials structure formation processes in the conditions of SPS. The structures of Cu-Cr, Cu-Mo, Cu-W, Cu-Cr-Mo, Cu-Cr-W, Cu-Mo-W, Cu-Cr-SiC, and Cu-Zr-CNTs two-component and three-component systems were analyzed. The possibility of the formation of non-equilibrium phases under SPS conditions is shown, the effect of chemical transformations on the structure of bulk composite materials is considered.
