The shock compression response of Al and Fe{sub 2}O{sub 3} powders has been studied with time-resolved pressure measurements using the PVDF stress-rate gauges, extending the early work of Holman {ital et al.} Experiments were performed on Al and Fe{sub 2}O{sub 3} powders, mixed in different volumetric distributions, corresponding to 50:50, 40:60, and 25:75 volumetric ratios. The shock-compression response demonstrates a complex effect of volumetric distribution on the densification behavior. The propagated stress wave-forms reveal a change in slope in the rise to peak pressure, indicating the influence of the differences in reactant properties. Differences in the crush strength in powder mixtures of different volumetric distributions are also observed, with the equivolumetric powder mixture showing crush-up to full density at lower pressures. {copyright} {ital 1998 American Institute of Physics.}
