Abstract: Microscopy, X-ray diffractometry and EBSD analysis were applied to inspect the relationships between deformation mechanisms and initial textures in polycrystalline magnesium alloys AZ31. It is found that different deformation mechanisms proceed according to theoretic prediction. Basal slips occur when basal planes of grains are tilted toward normal direction(ND) around transverse direcation(TD); prism slips dominate when basal planes are perpendicular to TD. {101-2} twinning was favored when basal planes are normal to rolling direction(RD) and {101-1} twinning is analyzed to be related to the basal orientation of grains.
