摘　　要：采用ODF分析法 (晶体取向分布函数法 )及SEM -EBSD(背散射电子衍射 )技术研究和分析了不同冷轧润滑剂下高纯铝再结晶立方织构的形成和发展 ,结果表明 ,采用机油和煤油作润滑剂冷轧高纯铝箔时 ,退火后再结晶织构都是由很强的Cube织构以及弱的R织构组成 ,但煤油润滑比机油润滑冷轧样品退火后获得强得多的立方织构。再结晶立方织构的形成和发展受冷轧形变织构及显微组织结构不均匀性的影响。煤油润滑时样品中产生了大量的不均匀变形组织———剪切带 ,带中存在大量的立方取向结构 ,它们提供了形核条件 ,强化了再结晶立方织构 ;而机油润滑时冷轧样品变形比较均匀 ,很难观察到剪切带组织 ,也很难发现有立方取向结构 ,说明形变轧制织构和剪切带中的立方取向结构直接影响并控制着再结晶立方织构的形成和发展。The formation and development of the recrystallized cubic texture of high-purity aluminium foils in the presence of different cold-rolling lubricants were studied and analysed using ODF and SEM-EBSD. The experimental Results showed that the recrystallized textures of high-purity aluminium foils consisted mainly of very strong cubic components and weak R-components. However, the sample obtained by cold rolling with kerosene as lubricant had much stronger cubic texture than with machine oil as lubricant. The formation and development of the recrystallized cubic texture were affected by the inhomogeneity of the deformation structure and microstructure during cold rolling. In the sample obtained by cold rolling with kerosene as lubricant, there were many inhomogenous deformation textures——shear bands, which have quantities of cubically-oriented structures. The structures provided the conditions for nucleis formation and intensified the recrystallized cubic structures. However, no shear band and no cubically-oriented structure were almost observed in the sample obtained by cold rolling with machine oil as lubricant due to its uniform deformation. This indicated that the formation and development of recrystallized cubic texture are affected and controlled directly by the rolling deformation textures and the cubically-orieated textures of the shear bands.
