The Computer Simulation of Rolling Texture

The simulation process of rolling deformation in matels is analysed, and a new deformation model (PC-model) is suggested. The new model modifies the shear condition of deformation grains in polycrystal, in which the shears are partially free, so that the simulation could further approach the real cases. According to comparison with rolling texture in Al polycrystal the PC-model could show more accurately the flow tendency of grain orientations in f.c.c matels and their final stable positions in orientation space.
