连铸AA5754和高铁AA5754铝合金的热轧带材在再结晶退火后沿轧制方向呈细长晶状分布。将退火后的热轧带材分别沿原始轧制方向和横向轧制到不同的变形量。用X射线衍射仪研究了晶型对织构演化的影响。结果表明，与横轧相比，直轧导致r-Cube+Cube组分的消失率较高，而β纤维组分的成形率略高。与斜轧相比，直轧时沿轧制方向的细长晶更容易从初始取向向β纤维旋转。
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 β fiber component than cross-rolling. The elongated grains in the rolling direction were easier to rotate from initial orientations to the β fiber in straight-rolling than in cross-rolling.
