On twinning and anisotropy in rolled Mg alloy AZ31 under uniaxial compression

The mechanical anisotropy of hot-rolled Mg alloy AZ31 is investigated both experimentally and numerically. First, five different specimen orientations with tilt angles of α=0°, 30°, 45°, 60° and 90° between the normal direction and longitudinal specimen axis are used to experimentally study the mechanical anisotropy under uniaxial compression. Then, the Elastic Visco-Plastic Self-Consistent (EVPSC) model, with the recently developed Twinning …
