摘要：

Two different types of shear textures were observed in cold rolled aluminum sheets after normal rolling without lubrication and after asymmetrical rolling carried out with the upper and lower rolls running at different velocities. Finite element simulations showed that the formation of the different shear textures could be attributed to differences in the strain history during rolling. The development of shear textures was quantified by assuming various idealized strain paths in polycrystal-plasticity deformation texture simulations. The net shear accumulating during a rolling pass plays an important role in determining the type of the resulting shear texture.
