Abstract
A physical model based on the single grain approach is refined to predict the recrystallization kinetics of a single-phase alloy following hot deformation. The model involves the original and deformed grain geometry, the characteristics of the dislocation networks formed during deformation, and the average mobility of the moving interfaces. The model properly accounts for the effect of the concurrent recovery and textural components in the deformed microstructure on the recrystallization kinetics. Plane strain compression (PSC) tests on an AA1050 aluminum alloy were used to simulate the hot rolling deformation and to provide the necessary input and validation data. Using internal state variables of known magnitude and a single value for the interfacial mobility, a very good agreement between the model predictions and the experimental data were obtained.
