Abstract

In this work, the behavior of powdered titanium mononickelide in static and shock compression and subsequent heating of the molds was studied using the methods of x-ray and dilatometric analysis. It was shown that during static compression, in distinction from shock compression, the phase transition B2 → B19 takes place to a significant degree in the powder. At the same time, shock compression causes significantly more lattice defects in comparison with static compression, which the process of subsequent sintering activates. During the sintering of the pressings produced by static compression, the reverse transformation takes place in them accompanied by the effect of shape "memory" and causing the distension of the molds, which complicates the production of high-density sintered material.
