Analyzing the Effect of High Pressures and Temperatures on the Formation of the Structure and Properties of WC–Co Hard Alloys

Abstract

The effect of barothermal (HPHT) treatment on the structure and properties of carbides of refractory metals and their alloys is considered. The principal directions of studies are determined. The comparative analysis of data measured in studying the mechanical properties of WC–Co hard alloys after sintering at high pressures and temperatures is performed. It has been established that the crucial role in the formation of the structure and mechanical properties of WC–Co alloys in the process of HPHT treatment is played by the process temperature under constant pressure conditions.
