Abstract

This paper demonstrates that aging prior to extrusion (APE) can greatly enhance the mechanical properties of an extruded Mg-7.6Al-0.4Zn alloy. The fine Mg₁₇Al₁₂ precipitates formed by APE reduce the average size of dynamically recrystallized grains and increase the amount of small Mg₁₇Al₁₂ particles present after extrusion, thereby improving the strength of the alloy. This APE treatment also enhances the ductility of the extruded alloy by decreasing the amount of large banded Mg₁₇Al₁₂ particles, and suppressing the serrated flow during tensile deformation.
