EXPERIMENTAL VERIFICATION OF MECHANICAL PROPERTIES OF THUNGSTEN HEAVY ALLOYS AFTER HOT ROTARY SWAGING AND ANNEALING

Abstract

This study deals with the experimental processing of a tungsten heavy alloy prepared by powder metallurgy using the technology of rotary swaging. Rotary swaging took place at a temperature of 900 ° C. After processing by rotary swaging, the material was further subjected to annealing. Emphasis was placed on the mechanical properties of the material before processing, after processing and after annealing. In the study we also deal with the influence of forming and annealing on the structural arrangement of tungsten heavy alloy.
