Abstract

Aluminium single crystals with {112}<111>, {110}<112> and {123}<412> orientations have been cold rolled with various L/d values. Texture development in the crystals has been investigated by means of pole-figure measurements and a topographical X-ray technique. In crystals rolled with L/d<1 inhomogeneous orientation distributions over the cross-section are observed. A layered structure has developed; within the layers the orientation changes gradually or remains constant, discontinuous orientation transitions are found between the layers sometimes. {110}<112> and {112}<111> crystals rolled with L/d retain their initial orientations, whereas in {123}<412> oriented crystals rolled under these conditions still layered structures are observed. The anomalous behaviour of crystals with the {123}<412> orientation points to a lower stability of this orientation with respect to rolling, compared to {110}<112> and {112}<111> oriented crystals.
