Title: Shock-induced chemical reactions in a Ni/Al powder mixture

Abstract

A new 50 mm powder gun was used to reproduce and to extend the real-time observations of ultra-fast exothermic reactions in a Ni/Al powder mixture at the shock front. Shock profiles measured by a manganin gauge show that (1) the threshold pressure for reaction is about 14 GPa; (2) the initiation criteria based either on shock energy or melting are in contradiction with experimental evidence. {copyright} {ital 1997 American Institute of Physics.}
