Localization of plastic deformation in Cu and Ni single crystals

The patterns of plastic flow in fcc Cu and Ni single crystals oriented in a way to provide easy slip are studied. The main space-time characteristics of deformation localization at the stages of easy slip and linear strengthening in these single crystals are established. The relation between the orientation of the sites of deformation localization and the crystallography of the slip systems in the samples is studied. The velocity of the motion of the deformation-localization sites during sample tension is determined.
