Modeling of severe deformation and mechanical properties in Mg-3Al-1Zn alloy through asymmetric hot-extrusion
چکیده انگلیسی

One-pass asymmetric hot extrusion performed at 673 K was applied to fabricate an AZ31 magnesium alloy sheet. Finite element method (FEM) was used to model the process of asymmetric hot-extrusion. Simulation results indicate that strain rate gradient through the thickness introduced a grain size gradient along the thickness direction and shear deformation during the asymmetric hot-extrusion results in weakened and tilted (0002) basal texture. The asymmetric hot extrusion effectively weakens the basal texture and improves the ductility at room temperature.
