Coupling crystal plasticity and cellular automaton models to study meta-dynamic recrystallization during hot rolling at high strain rates

Predicting microstructure and (micro-)texture evolution during thermo-mechanical processing requires the combined simulation of plastic deformation recrystallization. Here, a approach based on coupling full-field dislocation density crystal plasticity model cellular automaton is presented. A regridding/remeshing procedure used to transfer data between deformed mesh large-strain regular grid automaton. Moreover, physics nucleation criterion has been developed difference changes in orientation due deformation. The framework study meta-dynamic recrystallization double-hit compression tests multi-stand rolling high-resolution representative volume elements. These simulations reveal good agreement with experimental results terms texture evolution, mechanical behaviour growth kinetics, while enabling insights regarding effect kinetics crystallographic evolution.
