THE TEMPERATURE DEPENDENCE OF SHOCK WAVE PROPAGATION IN BRASS AND ALUMINUM,
Abstract
Measurements at initial temperatures ranging from 20C to 450C reveal an anomalous effect of pre-heating on shock wave propagation in brass. The shock wave velocity observed at 20C is decreased about 20% at 450C for equal incident pressures. The anomaly is attributed to a disorder-order rearrangement occurring in Cu-Zn alloys of near stoichiometric composition. Pre-heated aluminum was observed to behave normally under dynamic compression. Relations were derived for computing the variation of the Gruneisen parameter with volume using the slope and intercept of the shock velocity - particle velocity curve and the initial temperature of compression.
