Structural transformations and strain effects in copper and copper-base alloys due to dynamic loading

The strain behavior and phase transformations in Cu-37 wt.% Zn brass, Cu-12.5 wt.% Al bronze, and copper (99.97%) are studied under two variants of pulse loading, i.e., converging shock waves and a flux of powder particles accelerated by explosion. The effects connected with uniform and localized strain caused by the action of shock waves are determined and the disperse structures formed in the materials under dynamic loading are analyzed. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 3, pp. 28–34, March, 2007.
