Effect of rolling geometry and surface friction on cube texture formation

It is shown via texture simulation that redundant shear deformation during rolling has an important influence on the amount of cube oriented material in cold rolled fcc metals and hence on the cube recrystallisation texture. A small amount of redundant shear enhances the development of the cube recrystallisation texture, whereas a large amount of shear suppresses it. The maximum volume fraction of cube oriented material is obtained in the deformed structure when the ratio of the shear to normal deformation is -0·3. This corresponds to the typical condition found in laboratory rolling. It is further predicted that the density of cube oriented material is a complex function of position in the specimen thickness direction, and this function itself changes according to the rolling conditions. © 1994 The Institute of Materials.
