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 1.2 8,形变量为 99.2 %时 ,随厚度的增加 ,呈现出极有规律的变化 :{ 10 0 }丝织构含量近线性减少 ,而 { 112 } ,{ 10 2 } ,{ 12 3}丝织构含量近线性增加。当形变量为 99.2 %时 ,在不同速比下 { 0 0 1}丝织构含量沿厚度变化趋势不同 :速比 1.2 8时 ,呈现出近线性递减 ;速比 1.17和 1.0 6时 ,总的趋势也是递减 ,且在厚度d =0 .0Textures 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.
