An electron microscope investigation of explosively loaded copper

Abstract

Single crystals of copper subjected to shock pressures of 63 kbars were examined by transmission electron microscopy. Dislocation substructures in planes perpendicular and parallel to the shock front showed a striking difference in their nature and distribution. Polycrystalline copper specimens subj ected to pressures from 90 to 150 kbars were also examined. The changes observed on annealing are discussed.
