Numerical Simulation of Recrystallization and Phase Transformation during Intercritical Annealing in a Cold-rolled Dual-Phase Steel
A modified two-dimensional (2-D) cellular automaton (CA) model is developed to simulate the concurrent ferrite recrystallization and austenitic transformation during intercritical annealing of cold-rolled Dual-Phase steels.In this model,discrete microstructural constituents either in recrystallization or in phase transformation are depicted through involving relevant thermodynamic criteria (stored deformation energy,chemical transformation driving force,etc.) and kinetic effects (grain boundary mobility,carbon diffusion,etc.),so that a detailed microstructural insight into the mutual interactions between these various metallurgical processes can be obtained.This model is also able to study the influence of initial heating rate on subsequent isothermal transformation kinetics and the associated microstructure evolution.
