Enchasing the mechanical properties of heavy pseudo-alloys of tungsten by high-voltage electric pulse impact

Abstract

The article presents a study of the effect of the high-voltage electric pulse modes of impact under pressure on the structural and mechanical properties of compacts of heavy tungsten alloy VNZh 7-3. Identified an increase in density of material, in microhardness and tensile strength with voltage increase in high-voltage discharge. The optimum exposure mode determinate, which provides the highest level of strength and ductility of the sintered material.
