Abstract
For steel and copper as example, the processes of structure formation are considered, taking place under the conditions of intense plastic deformation which is initiated by different kinds of dynamic loading in the zone of contact between the metals of different kinds. It is shown that intense plastic deformation promotes an increase in mutual solubility metals in each other and the formation of atomically ordered phases. In the case of ultrahigh pressure, the formation of atomically ordered phases was not detected. This is connected with the fact that the free atomic volume in the liquid phase, formed in the cumulative jet, exceeds the free volume during solid-phase interaction. A set of the models of structure formation under the gradient conditions can be united within the framework of the scheme “shear-turn”.
