Modeling of non-isothermal annealing: Interaction of recrystallization, recovery, and precipitation

A procedure for modeling recrystallization in the course of non-isothermal heat treatments is introduced. For this purpose a three-dimensional cellular automaton is utilized. The model is capable of predicting the microstructure, texture, and kinetics. A special focus is laid in this study on the complex interactions of recrystallization with recovery and precipitation. The model is applied to a commercial Al–1 wt.% Mn alloy cold rolled and annealed using heat treatments with different temperature–time profiles. The resulting microstructures and recrystallization kinetics are compared with experimental data.
