　　The concurrent ferrite recrystallization and austenitic transformation during intercritical annealing of cold-rolled DP steels is investigated by cellular automaton (CA) modeling.The simulations provide insight into the microstructural phenomena that result from the interaction of primary recrystallization and phase transformation.We find that the interaction between ferrite recrystallization and austenite formation affects not only the transformation kinetics but also the morphology and spatial distribution of the austenite.From this we can interpret experimental data of the observed temperature-dependent hardness and its dependence on the two metallurgical processes.The influence of the initial heating rate on subsequent isothermal transformation kinetics and the microstructure evolution is also obtained by the model.
