Analysis of anisotropy of extruded magnesium alloy AZ31 bar

The large strain Elastic Visco-Plastic Self-Consistent (EVPSC) model, with the recently developed Twinning and De-Twinning (TDT) description, is applied to study the mechanical behavior of magnesium alloy AZ31 extrusion. Five different specimen orientations with tilt angles of α of 0°, 22.5°, 45°, 67.5° and 90° between extrusion direction and longitudinal specimen axis are used to study the mechanical anisotropy under both uniaxial tension and …
