Abstract
The influence of shock loading on the residual strength of RMI 38644 has been examined. Shock loading below 70 kbar resulted in a reduction in the residual/terminal strength. This decrease is thought to be due to the interaction of the planar shock wave and the initial microstructure. It is proposed that at low pressures the passage of the shock wave results in the reversion of athermal omega. Higher shock pressures yield increased dislocation densities and consequently higher yield strengths.
