Abstract:The rolling textures of pure aluminum were simulated with the modified relaxed constraints (lath) model. The minimum shear of e13 was introduced to solve the ambiguity of the selection of the active slip systems and thus to satisfy the strain compatibility to the maximum extent. The results of computer simulation showed a good consistence with the measured rolling textures of pure aluminum. The orientation density f(g) calculated by the RC (lath) model is much closer to the measured than by the FC model.

 

Key words: aluminum rolling texture RC lath model minimum shear principle
