摘要：

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.
