Enhanced Brass texture of hot-rolled Al-4Cu-1.6Mg alloy by 0.1% Zr addition

The addition of 0.1 wt% Zr in Al-Cu-Mg alloy contributes to the formation of a stronger Brass and weaker Goss textures during hot rolling. Aiming at this observation, the related texture formation mechanisms are discussed from the aspect of dynamic recrystallization (DRX) behavior and phase particle effect on grain rotation. This work demonstrates that the low degree of DRX and grain rotation behavior by S phases are essentially re-sponsible for the enhanced Brass texture in Al-Cu-Mg-Zr alloy.
