EFFECT OF ROLLING GEOMETRY AND SURFACE FRICTION ON CUBE TEXTURE FORMATION

It is shown via texture simulation that redundant shear deformation du ring rolling has an important influence on the amount of cube oriented material in cold rolled fcc metals and hence on the cube recrystallis ation texture. A small amount of redundant shear enhances the developm ent of the cube recrystallisation texture, whereas a large amount of s hear suppresses it. The maximum volume fraction of cube oriented mater ial is obtained in the deformed structure when the ratio of the shear to normal deformation is approximately 0.3. This corresponds to the ty pical conditions.
