摘　　要：采用异步轧制技术对高纯铝箔进行冷轧,利用加热和在冷水中淬火,把样品的高温态保存下来。通过ODF分析和反极图定量计算,对高纯铝箔微取向流变行为进行了研究。结果表明:立方织构{001}<100>是在再结晶退火过程中形成和发展的;适宜的速比,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{001}<100>的前提。根据形变与再结晶理论,探讨了异步轧制高纯铝箔中立方织构{001}<100>的形成和发展。A state of high temperature in sample was kept by heating and quenching in cold water after cross shear rolling.Then the formation and development of cube texture ({001}<100>)of high purity aluminum foils was investigated by means of orientation distribution functions (ODFs) analysis and quantitative analysis of inverse pole figure.The results show that cube texture ({001}<100>)was formed and developed during process of recrystallization. Appropriate speed ratio, corresponding deformation reduction and heat treatment suited to these were preconditions to obtain strong cube texture ({001}<100>).The formation and development of cube texture ({001}<100>)of high purity aluminum foils after cross shear rolling was investigated based on theory of deformation and recrystallization.
