Effect of Rolling Reduction on the P {011} ⟨455⟩ Recrystallization Texture in a Supersaturated Al-Mn-Mg Alloy

The hot band of a continuous cast (CC) Al-Mn-Mg alloy was cold rolled to different reductions ranging from 0 to 90 pct and then annealed at 482 degrees C for 3 hours. The effect of rolling reduction on the P recrystallization texture was investigated by X-ray diffraction. The results show that the recrystallization texture of the hot band is characterized by weak P orientation and 22.5 deg normal direction (ND) rotated cube orientation. The strength of the P texture increases with increasing rolling reduction. After 90 pct cold rolling, the recrystallization texture of the cold-rolled sheet is dominated by a strong P component.
