Abstract
Based on analyzing experimental data and existing theoretical approaches, this study has formulated concepts of regular change in scenarios of phase transformations developing under severe plastic deformation. Depending on the temperature and deformation conditions, the dissipation of delivered energy can be realized by various routes (dislocation glide and climb, dynamic recrystallization, amorphization, and redistribution of alloy components), giving rise to a diversity of observed phase and structural states. A diagram of nonequilibrium states of alloy as a function of conditions of severe plastic deformation has been proposed. The applicability of the presented concepts has been demonstrated for a wide range of alloys and compounds.
