Abstract : In this research, the synthesis reactions of Ni and Al powder mixtures at the shock front in exothermic mixtures were studied. An existing, but non-functioning, two-inch diameter gas gun was modified into a powder gun to accommodate higher velocities of impact and larger specimen size requirements. Effects of impact velocity and particle size of the constituents on reaction kinetics were determined. The unique experimental data is currently being used to guide the development of models aimed at describing the shock wave interaction with exothermic mixtures with the goal of a better understanding of the formation of intermetallic compounds.
