Relationships between deformation mechanisms and initial textures in polycrystalline magnesium alloyw AZ31

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 de-formation mechanisms proceed according to theoretic prediction.Basal slips occur when basal planes of grains are tilted toward normal direction(ND) around transverse direction(TD);prism slips dominate when basal planes are perpendicular to TD.{10-↑12} twinning was favored when basal planes are normal to rolling direction(RD) and {10-↑11}twinning is analyzed to be related to the basal orientation of grains.
