Abstract: The effect of hot finishing rolling temperature on cube texture in high purity aluminium foils was investigated by means of orientation distribution functions (ODFs). The results show that a relatively strong rotated cube orientation ｛100｝〈011〉 exists when the end temperature of hot finishing rolling is 290 ℃, and the cube texture is the strongest after the final recrystallization. The cold rolling textures are comprised of S- , Cu-and Bs-components, andthe orientation ｛100｝〈011〉 is unstable, it may be split and evolved into two complementary copper components (112) ［-1,-1,1］and (-1,-1,2)［111］ during the cold rolling. And a sharp cube recrystallization texture would nucleate and grow in the deformation matrix with the Cu-orientation.
