摘要：
We investigate structure formation of metals undergoing severe plastic deformation. We present two natural assumptions that reveal valuable information about this process. The assumptions are the self-similarity of grain refinement and micro-damage and the complementarity of these two processes. Based on these assumptions, we obtain a system of kinetic equations that explains the formation of structure and suggests new problems for experimental and theoretical investigations.
