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. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
