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.
Keywords: copper; severe plastic deformation; continuous dynamic recrystallization. |
