Deformation and recrystallization textures in straight-rolled and pseudo cross-rolled AA 3105 aluminum alloy

Abstract The hot band of CC AA 3105 aluminum alloy was cold-rolled to different reductions along the original rolling and transverse directions, and then annealed at 427 °C for 24 h. The deformation and recrystallization textures in these cold-rolled sheets were investigated by X-ray diffraction. The result shows that further rolling of the hot band along the original rolling direction incrementally strengthens the β fiber rolling texture. Under cross-rolling (i.e., along the original transverse direction), the former β fiber orientations are unstable and they gradually rotate towards the β fiber in the new sample reference system. The recrystallization is completed at a lower reduction in the cross-rolled specimens than in the straight-rolled specimens. The recrystallization texture of the straight-rolled specimens is characterized by the major P component and the minor R and Goss components. The recrystallization texture of the cross-rolled specimens depends on the cross-rolling reduction. As the cross-rolling reduction increases from 33% to 90%, the recrystallization texture is changed from the {0 1 2} texture through {1 11 7} to the P texture.
