Non-equilibrium features of continuous recrystallization process at severe plastic deformation of copper


It is shown that separation of scalar dislocation density into two parts, giving densities of mobile and immobile dislocations, is providing a possibility to predict continuous dynamic recrystallization (DRX) process caused by severe plastic deformation of metallic materials. The proposed approach is making it possible to predict a rather extent set of material microstructure properties that can be measured experimentally, based on a minimum set of "tuning" parameters. Received predictions are verified by comparison to experimental results and predictions received using another known dislocation plasticity and dynamic recrystallization models.
