摘要

A modified cellular automaton model, coupled with fundamental metallurgical principles of dynamic recrystallisation, is proposed to simulate microstructural evolution during thermomechanical processing. The effects of key processing parameters on the characteristics of dynamic recrystallisation are taken into account in the model, which is able to predict plastic flow behaviour and the size of dynamically recrystallised grains. Simulation results illustrate the expected performance in agreement with the experimental results of pure nickel deformed at a specified deformation temperature. Simulation results also indicate that, in a given condition, the mean grain size and percentage of dynamic recrystallisation increase with the increase of temperature and decrease with the increase of strain rate.
