Effect of grain size distribution and texture on the cold extrusion behavior and mechanical properties of AZ31 Mg alloy

▶ Microstructure and mechanical properties of fine-grained AZ31 Mg alloys were studied. ▶ The initial homogeneous microstructure led to homogeneous cold deformation. ▶ Texture softening effect on yield strength overcame fine-grain strengthening effect. ▶ Well-distributed grain size reduced the absolute difference of yield strength.
