Abstract
This paper is concerned primarily with the direct observation of shock-induced defect microstructures in 70/30 brass, 304 stainless steel and copper; and the attempt to relate the microstructural features observed with experimentally determined mechanical properties. The method of direct observation utilizes both bright- and dark-field transmission electron microscopy. Some attention is also given to the relationship of shock-induced defect structures to those resulting from conventional modes of deformation such as simple compression and cold reduction by rolling. It is shown, through the use of the electron microscope, that structures in stainless steel vary greatly with the mode of deformation. Some consideration is also given to the apparent role of stacking-fault energy in determining residual-shock structures in fcc metals and alloys.
