Evolution of Goss texture in an Al–Cu–Mg alloy during cold rolling was investigated by three-dimensional orientation distribution functions, electron back-scattered diffraction and transmission electron microscopy. The results showed that with increasing reduction from 23.7 to 80%, Goss textures gradually transformed into Brass texture through the activation of sole {111}<110> slip systems. When rolling reduction further increased from 80 to 86.3%, Goss texture rather than Brass started to rotate towards Copper and S components. The formation of Copper and S textures at these high reductions was attributed to the activation of {110}<110> and {001}<110> non-octahedral slip systems.

Al-Cu-Mg合金冷轧过程中戈斯织构的演变

通过三维取向分布函数，电子背散射衍射和透射电子显微镜研究了Al-Cu-Mg合金在冷轧过程中高斯织构的演变。结果表明，从23.7％降低到80％，高斯织构通过激活唯一的{111} <110>滑移系统逐渐转变为黄铜织构。当轧制压下率从80％进一步增加到86.3％时，高斯织构开始向铜和S组分旋转，而不是黄铜。在如此高的还原率下，铜和S织构的形成归因于{110} <110>和{001} <110>非八面体滑移系统的激活。
