A recently advanced model for the shock consolidation of powders predicts, for a powder of given distension, the regimes of shock pressure and shock duration expected to yield fully densified compacts of near optimum strength. The model is evaluated in terms of UTS measurements in compacts of rapidly solidified powders of AISI 9310 alloy, shocked to initial shock pressures between 3.6 and 17.9 GPa and to shock durations between 0.23 and 2.1 μs. We find that in powders of distention 1.7, shock durations > 1 μs are required at 10 GPa to properly solidify the melt.
