摘    要:采用EBSD微取向分析方法,通过分析高纯铝箔冷轧后退火的再结晶初期立方取向晶核的形成过程及立方取向晶粒的长大行为,探讨了高纯铝箔中立方织构形成的微观过程.结果表明,在高纯铝箔轧制基体上没有发现立方取向{001}<100>的晶核优先形成,但是再结晶完成以后却会出现较强的立方织构,因此高纯铝箔立方织构的形成主要是借助于立方取向晶粒的取向生长机制实现的.立方取向晶核容易在S取向{123}<634>的形变晶粒之间产生.

关 键 词:高纯电子铝箔  立方织构  形成过程  冷轧  退火  再结晶  微观过程  立方取向  电容器  电极

Abstract:The micro-process of cube texture formation in high purity electronic aluminum foils was investigated by EBSD (Electron Back Scattering Diffraction) technique in SEM and the related analysis of crystal orientation. The nucleation and growth behavior of cube orientation grains in the early stage of recrystallization were discussed and analyzed during the annealing of cold rolled aluminum foils. The results show that the nuclei of cube orientation {001 }<100> are not frequently observed in the rolled matrix, however, high purity aluminum foils hold strong cube texture after recrystallization. Cube texture formation abides by the mechanism of preferred growth, and the nuclei of cube orientation frequently form in the deformed matrix with S orientation grains {123}<634>.
Keywords:high purity aluminum foil  cube texture  EBSD  recrystallization
