Abstract

Abstract

In this paper, two different sizes of high-speed-steel powders have been mixed and then consolidated dynamically by means of a cylinderical converging explosive method with a ring-shape flyer. It has been found that the behaviors of large powder particles differ from that of small powder partieles. After the passage of shock-wave the energy absorption on small powder particles is much greater than that on large powder particles, so that the small power particles may melt prior to large powder particles.
