摘要：

The hot bands of continuous cast AA 5754 and high-Fe AA 5754 aluminum alloys exhibited elongated grains in the rolling direction after recrystallization annealing. The annealed hot bands were cold rolled to different reductions along the original rolling direction and transverse direction, respectively. The effect of grain shape on texture evolution was investigated by X-ray diffraction. It was found that straight-rolling resulted in a higher rate of disappearance of the r-cube + cube component and a slightly higher rate of formation of the beta fiber component than cross-rolling. The elongated grains in the rolling direction were easier to rotate from initial orientations to the beta fiber in straight-rolling than in cross-rolling. (C) 2010 Elsevier B.V. All rights reserved.
