Abstract: Textures distribution along the thickness after cross shear rolling of high purity aluminum foils was investigated. The results 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 1.28 and deformation 99.2%, with increase of thickness, the volume fraction of {100} fiber shows the nearlinear 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 change 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 between the slow side surface and the fast side surface, and the minimum is formed at the thickness .d=0.04mm side.
Textures distribution along thickness after cross shear rolling of high purity aluminum foils
Abstract:
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.
