Notes:
The aims of this study ares to investigate the microstructure evolution of AZ31 Mg alloyswith normal rolling and different speeds rolling during hot rolling affects microstructure, textureand mechanical properties of AZ31 Mg alloy. In the microstructures of as-rolled both samples,twins are clearly apparent, small and recrystallized grains are visible along some grain boundaryand twinned regions. The tensile strength and yield strength of DSR sample were slightly higherthan that of NR sample. Also, in the case of the NR sample, tensile strength indicated differentvalues to the rolling directions. From this result, NR sample compared to DSR sample stronglyindicated to the plastic anisotropy tendency. Therefore, it is noted that DSR sample could bepresented to the good formability, comparing to the NR sample. DSR samples deformed at 473Kand 523K could be perfectly formed, indicating the potential application of the DSR process toimprove formability of the Mg alloys at warm temperatures
