The Mg-3Al-1Zn magnesium alloy sheets rolled at 573 and 798 K characterized by strong and weak basal textures, respectively, were further subjected by a single high temperature rolling pass at 798 K. The sheet rolled only at 798 K throughout rolling exhibits a double peak texture in both of as-rolled and annealed conditions. By contrast, for the sheet rolled at 573 and 798 K, the reduction rate of basal texture intensity is larger and the single peak of the rolling texture changes to the double peak with basal poles largely tilting in the RD at similar to 20 degrees after annealing, which is rarely observed in wrought magnesium alloys. This phenomenon is resulted from static recrystallization and may be related to enhanced pyramidal < c + a > slip during high temperature rolling due to the initial strong basal texture.
