Description:
Magnesium alloy AZ31, which processed by conventional rolling or extrusion, has highanisotropy of mechanical properties in its strength and elongation at room temperature. We comparedthe influence of differential speed rolling with conventional rolling process on microstructure andmechanical properties of commercial AZ31 sheet. Commercial AZ31 alloy sheets were processedwith conventional and differential speed rolled with thickness reduction ratio of 30% at a varioustemperature. The elongation of AZ31 alloy, warm-rolled by differential speed rolling is larger thanrolled by conventional rolling. Besides, grain size and distribution on microstructure of theconventional rolling were coarsely(~30μm) and inhomogeneously but, that those of the differentialspeed rolling were fine(~13μm) and homogeneously.
