Abstract

A conceptual analysis of approaches to describing concentration heterogeneities and structural and phase transformations in submicroscopic and nanocrystalline aggregates formed by cold severe plastic deformation (SPD) is given. The decisive role of the vacancy diffusion mechanism in forming chemical heterogeneities in activated alloys is demonstrated. The concept of the nonequilibrium hole gas and the disclination-dislocation deformation mechanism is used to develop a model approach to describing the behavior of metal systems produced by SPD. Model calculations are compared with experimental data and the main trends for further refining of the model of activated alloy formation are formulated.
