摘要 采用X射线衍射仪研究3105铝合金在横轧过程中织构的演变。结果表明:3105铝合金热轧板材具有强的β纤维轧制织构,在横轧过程中B′{110}<111>、S′{123}<17229>和C′{112}<110>取向是不稳定的,它们将逐渐向新的坐标系中β纤维的位置旋转;随横轧压下量增大,C′和S′取向强度快速降低,B′取向强度先增加后降低,而β纤维轧制织构的强度逐渐增加;β纤维和剩余组分织构体积分数的变化与轧制真应变的关系遵循Avrami方程,强的初始B′、S′和C′织构显著地提高了β纤维织构的形成速率。 The hot band of continuous cast 3105 aluminum alloy was cold rolled to different reductions along the original transverse direction. The texture evolution during cross-rolling was investigated by X-ray diffractometry. The results show that the hot band of 3105 aluminum alloy possesses a strong b fiber rolling texture. After 90? rotation about the normal direction, the typical B, S and C orientations on the b fiber transform into the B¢{110}á111?, S¢{123}á17229? and C¢{112}á110? orientations. These orientations are unstable and gradually rotate to the b fiber in the new sample reference frame. As the rolling reduction increases, the intensities of the C¢ and S¢ orientations decrease, while the intensity of the B¢ orientation first increases and then decreases. At the same time, the strength of the b fiber rolling texture increases with increasing rolling reduction. The variation in the volume fractions of the b fiber and remainder components with rolling true strain follows the Avrami equation. The strong initial B¢, S¢ and C¢ textures significantly increase the formation rate of the b fiber rolling texture.
