Abstract

Copper single crystals with the {110}[001] initial orientation were cold rolled and subsequently compressed in a channel die with the new direction of plastic flow parallel to the former transverse direction of rolling. The texture formed during subsequent recrystallization showed components which were not characteristic for the texture of the deformed matrix. Shear bands were formed after the change in the direction of plastic flow. Recrystallization commenced within shear bands and proceeded by the growth of selected grains into the deformed matrix. Measurements of the local crystallographic orientations indicated that the processes predicted by the theory of oriented growth played an important role in the formation of recrystallization textures. The orientations of the fast growing grains could be produced as a result of the formation of recrystallization twins.
