Abstract：AZ31 magnesium sheets with different initial widths were rolled under the same conditions.Hardness test,XRD and SEM experiments were used to investigate the effects of initial widths on microstructures and properties of rolled AZ31 magnesium sheets.The results show that the initial width has some effects on the rolled AZ31 magnesium alloy sheet.With the initial width increasing,the hardness at the edge of the rolled sheet becomes higher,more recrystallized grains are generated,and(0002)basal plane orientation XRD peaks are enhanced.At the central part of the rolled sheet,dynamic recrystallization occurs more completely,the hardness in the center is lower than that at the edge,(0002)basal plane orientation increases dramatically.
