摘　　要：利用取向分布函数 (OrientationDistributionFunctions)分析和反极图定量计算 ,探讨了异步轧制下 ,高纯铝箔织构的形成和发展。结果表明 ,适宜的轧辊速比 ,相应的形变量和与之相匹配的退火工艺 ,是获得强立方织构(10 0 ) [0 0 1]的前提。当轧辊速比为 1 2 8、形变量为 96 7%时 ,在 6 0 0℃退火后 ,立方织构的体积分数高达96 6 5 %。The formation and development of cube texture (100) of high purity aluminum foils after cross shear rolling was investigated by means of orientation distribution functions(ODFs) analysis and quantitative analysis of inverse pole figure.The results show that very strong cube texture (100) can be obtained through combination of suitable speed ratio,corresponding deformation reduction and annealing process.As high as 96.65% volume percentage of (100) cube texture is obtained with a roller speed ration of 1.28,a reduction percentage of 96.7% and annealing at 600℃.
