Through-Process Modeling of Aluminum Sheet for Improved Property Predictions 2004-01-0182

We report on a novel approach for through-process modeling of anisotropy development during AA5182 sheet production from hot rolling through terminal annealing. For this a thermomechanical process model was coupled to physics based microstructure models for deformation texture (GIA), work hardening (3IVM), and recrystallization texture (StaRT). The model overpredicts the Cube texture during hot rolling but properly predicts the terminal texture after multiple cold rolling with intermediate annealing. This approach can be extended to forming of automative sheet or integrated in crash simulations.
