A physically based computer model has been developed to simulate recrystallization process in Fe-Si motor lamination steel. The model assumes that each component of recrystallization texture nucleates at different stage of the process and has its own orientation. The deformed texture and microstructure, stored energy and the microstructure prior to deformation are among the major factors in determining the recrystallization texture. The experimental results show that the model is capable of predicting recrystallization texture.
