Effects of Shock Loading Variables on Shock Wave Strengthening of Metals.

Abstract

The purpose of this research has been to determine the effects of shock loading variables on the microstructure and properties of shock hardened materials and to compare laser-induced shock pulse effects with those associated with mechanically introduced shock pulses. Of particular interest has been the extension of the study of pulse duration effects to very short durations; e.g., less than 0.01 micro second. Most earlier work had been done with pulse durations of 1 micro second or greater, where, as shown by the current study, the effects are time-saturated. In addition to measurements of the hardening effects, the shock-induced substructures have been characterized in detail with x-ray diffraction and transmission electron microscopy. (Author)
