Ni-Al Powder Mixture Initiation During Shock-Wave Loading and Heat Treatment

Abstract

This paper studies shock wave loading and heat treatment of a Ni-Al powder mixture in a metal matrix. We had found that a monophasic product NiAl was synthesized at the flyer plate velocity of 1500 m/s, immediately, or at 550 m/s during heat treatment (up to 750 °C) and for 3 hours heat treatment. Initiation temperature of powder mixture was about 600 °C. The results got are perspective for the development and production of composite materials with an intermetallic layer.
