Abstract:
We studied the effect of explosive loading on the microstructure and phase composition of the Ni–Al system in the course of SHS interaction. X-ray diffraction, micro x-ray diffraction, and optical methods established an appreciable effect of shock-wave loading on the structural characteristics of the synthesis products. A multistage character of SHS in the system in question was noted; the nature of shock-wave action is determined by the structure which has formed by the instant of loading. It is suggested to use the method of measurement of concentration inhomogeneity for studying the effect of a shock wave on the diffusion interaction in reacting systems.
