Abstract
Deformation anisotropy of samples from rolled sheet and extruded rod of AZ31 alloy was investigated in the present work. A strong basal plane texture is detected formed during rolling and extrusion, and both rolled and extruded samples exhibit similar mechanical behavior: tensile yield strength is the highest in the specimens parallel to the longitudinal direction, and decrease continuously as the specimen orientation departs from the longitudinal direction. Using texture analysis and optical microscopy it has been found that, the obvious anisotropy can be explained by texture and orientation factor during tension and compression. Basal slip and twinning are restricted when tensile load is applied in the rolling and extrusion direction, which results in high tensile yield strength along the two directions.
