摘　　要：应用取向分布函数研究和分析了退火对异步轧制高纯铝箔微取向的影响。结果表明：在异步轧制的试样中产生较强的(001),(110)旋转立方织构和(102)(uvw)织构。异步轧制后退火的高纯铝箔试样中,立方(001)(100)织构组分的形成存在一个“阈值温度”,此温度与异步轧制的速比成反比,随着速比的增加,“阈值温度”降低,这与异步轧制提高高纯铝箔的形变储能有关。适宜的速比,相应的形变量和与之相匹配的退火工艺,可以获得强的立方织构。The effect of annealing temperature on micro-orienlation in cross shear rolled high purity aluminum foils was investigated by means of orientation distribution functions （ODFs）. The strong rotated cube texture components {001}〈110〉 and {102}〈uvw〉 were formed and developed in cross shear rolled specimen. During the annealing of cross shear rolled specimen, there was a temperature threshold value for the formation and development of cube orientated grain and the value was inversely proportional to that of speed ratio. With increasing roll mismatch speed ratio, the threshold value decreased, which was related to deformation stored energy. Very strong cube texture could be obtained through the combination of suitable speed ratio, corresponding deformation and heat treatment.
