摘    要:通过异步轧制, 研究了高纯铝箔冷轧织构沿板厚的分布规律。 在异步轧制下, 快、 慢速辊侧之间的各中间层的织构类型不同。 速比为1.28, 形变量为99.2%时, 随厚度的增加, 呈现出极有规律的变化: {100}丝织构含量近线性减少, 而{112}, {102}, {123}丝织构含量近线性增加。当形变量为99.2%时, 在不同速比下{001}丝织构含量沿厚度变化趋势不同: 速比1.28时, 呈现出近线性递减; 速比1.17和1.06时, 总的趋势也是递减, 且在厚度d=0.04mm处有最小值。

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 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 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.
