The dislocation structure was free from inhomogeneities with high orientation changes normally observed in deformed materials. After reductions 20% and 40% against the background of cells there were sometimes observed bands (dislocation rich layers). With increasing strain the cell structure became faint and the dislocation rich layers became sharper (after 60% reduction no dislocation cells were revealed). It has been found, that in layers lying close to the rolled surface of the specimen the dislocation bands were nearly parallel to the RD and much thinner than those in further layers. SAD analysis indicate that in the surface layers the crystallographic orientation changed systematically with increasing distance from the surface to the center of the specimen (rotation around ND). In the intermediate layers the dislocation bands were curved and overlapped the other dislocation bands. Despite of detailed investigation shear bands were not observed even in specimens rolled to the 95% reduction.
