Effect of strain hardening on texture development in cold rolled Al-Mg alloy

The hot band of a continuous cast Al-Mg alloy possesses a typical deformed structure and a strong β fiber rolling texture. The hot band was heat-treated at 260 °C for 3 h to generate different degrees of strain hardening. The hot band and its counterpart after recovery treatment were cold rolled to different reductions along the original transverse direction. The effect of strain hardening on texture evolution was investigated by X-ray diffraction. The results show that a high degree of strain hardening reduces the formation rate of the β fiber rolling texture.
