Analysis on Effects of Strain Rate to Dynamic Recrystallization Process of Metals by 2-D CA Model

Article Preview

Abstract:

A tow-dimensional Cellular Automaton model has been established to simulate dynamic recrystallization (DRX) process of metals. The model considers the process of dynamic recovery, dislocation density, nucleation rate and etc on DRX. The variation of dislocation density, recrystallization-grain (R-grain) shape, orientation and mean size of R-grains can be detected during the whole deformation process. The simulated results agreed well with classical theory of growth kinetics. The effects of strain and strain rate to DRX and R-grains are discussed in the end of this paper. The percentage of DRX and mean size of R-grains are related with both strain and strain rate.
