ADVANTAGES OF HIGH VOLTAGE CONSOLIDATION OF HAFNIUM CARBIDE POWDERS AND TUNGSTEN-BASED ALLOYS

Abstract

The main features of high-voltage electropulse consolidation (H-VEC) of powder materials and the unique possibilities of the method caused by them are considered. The electrothermal processes in the H-VEC at the contacts between the powder particles and in the macroscale of the whole consolidated sample are analyzed. The results of calculations of the dynamics of closure (collapse) of interparticle pores in the consolidated material are presented.
