摘要：

Mg-Al binary alloys in the concentration range from 0 to 4.0 wt.% Al have been prepared under conventional casting conditions. The as-cast Mg and Mg-Al alloys after solution treatment were processed via hot extrusion at 350 degrees C. The results show that Al has a positive influence on grain refinement and solution strengthening. The as-extruded Mg-Al alloys are fully recrystallized, and the tensile yield strength of the binary alloys is two times higher than that of pure Mg. Furthermore, the elongations of Mg-Al alloys are much higher than that of pure Mg. In addition, Mg and Mg-Al alloys were further studied by the viscoplastic self-consistent (VPSC) model to explore the activation and evolution of deformation modes. The simulation results match well with the experimental results.
