Abstract
The shock‐compression and reaction response of equi‐volumetric micron‐scale (∼50–60% dense) spherical nickel and aluminum powder mixtures is investigated in the range of the calculated crush‐up pressure (P = 0.4 GPa) and up to 6 GPa. Time resolved stress measurements (using PVDF gauges) coupled with VISAR data is used to determine the shock states. Evidence of reaction or lack thereof is inferred by comparing the measured states with calculated Hugoniot state of reaction products based on the ballotechnic model proposed by Bennett and Horie, (Shock Waves 4:127–136). Post‐impact micro‐structural analysis of recovered material and comparison of calculated and measured product states is used to establish the criterion for reaction occurring in the shock or post‐shock states.
