Evolution of Goss texture in an Al-Cu-Mg alloy during cold rolling

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.
