Abstract
A recent investigation of powdered Ni‐Al systems subject to shock loading has yielded evidence that reactions occur during the shock front. Time‐resolved measurements of normal shock pressure indicate that an ‘‘excess pressure’’ is generated possibly due to an exothermic reaction in the Ni‐Al system. These reactions appear to occur during the 100 ns that represent the shock front. A clear reaction threshold is observed and corroborated by micrographs of the recovered samples.Keywords
