Abstract
A coupled mathematical model has been developed that predicts a microstructure evolution and a flow stress during and after the process of deformation. A part of the model, which is responsible for the microstructure evolution, consists of models of a recrystallization and a grain growth. A dynamic, static and metadynamic recrystallization is considered as a whole. The flow stress is calculated on the basis of the dislocation theory. Changes of the dislocation density during the deformation are described by model considered the hardening, the recovery and the recrystallization. In pauses between deformation process, the recrystallization is the only process taken into account as a softening one. The results of the simulation are demonstrated.
