One of the benefits of using high speed rolling for Mg alloys is for improving the hot rollability. In this study AZ31 and four Mg-Zn-Ce alloys were investigated under number of different rolling schedules. At a rolling temperature of 450 °C and rolling speed of 1000 m/min, the peak intensity of the (0001) pole figure tilted 10-15° towards the RD direction to form a double peak texture for both AZ31 and Mg-Zn-Ce alloys. A texture variation through thickness was observed. From the surface to the center of thickness, the direction of the (0001) peak TD-split rotated 90°. After annealing, the basal texture component of the Mg-1Zn-1Ce magnesium alloy sheets was weakened, and replaced by a new component rotated 45 ° towards the transverse direction. The hot tensile tests results confirm that the Mg-1Zn-1Ce alloy sheets with this non-basal texture component exhibit a higher ductility than the alloys with basal texture.
