Abstract: This work mainly investigated the effects of rolling speed on the microstructures, room-temperature mechanical properties, and stretch for-mability of AZ61 magnesium alloy sheets processed by two-pass hot rolling-shearing-bending (T-HRSB) and subsequent annealing (T-HRSBA). Electron backscatter diffraction (EBSD) analysis was employed to characterize the microstructures of sheets produced at three diffe-rent rolling speeds. Increasing the rolling speed promotes the activation of both {1012} extension twinning and dislocation slip within the T-HRSB sheets. Furthermore, higher speeds effectively weaken the intensity of basal texture (c-axis//ND) while simultaneously facilitating the formation and strengthening of the RD-texture component (c-axis//RD). At a lower rolling speed (0.1 m/s), the T-HRSBA sheet exhibits basal texture characteristics. With increasing of rolling speed, the intensity of the basal texture is continuously weakened, while the pole density distribution is broadened significantly along the RD and the pole density peaks shifts towards RD. Ultimately, a distinctive RD-split double-peak non-basal texture develops. In addition, the increase in rolling speed markedly enhances both the elongation after fracture and room-temperature formability of the T-HRSBA magnesium alloy sheets.
