Textures distribution along the thickness af te r
cross shear rolling of
high purity aluminum foils was investigated. The
result s show that large difference of cold rolling textures exists in the intermediate layer between the slow roller side and the fast roller. For the speed ratio 1.2 8 and deformation 99.2%, with increase of thickness, the volume fraction of {100 } fiber shows the near-linear decrease, however, the volume fraction of {112}, {102}, {123} fibers takes the near-linear increase. For the deformation 99.2%, there exist different tendency of change for the volume fraction of {001} fiber through the thickness at different speed ratios. For the speed ratio 1.28, the c hange of volume fraction of {001} fiber with the thickness presents near-linear decrease. For the speed ratio for 1.17, 1.06, the total tendency is also near- linear decrease. The relatively strong volume fraction of {001} fiber exists bet ween the slow side surface and the fast side surface, and the minimum is formed at the thickness d =0.04 mm side.
