Since age-hardening responses of magnesium alloys are poor, precipitation hardening has not been used in conventional wrought magnesium alloys. However, optimizations of alloy compositions often lead to the formation of metastable nano-sized precipitates such as Guinier Preston (G.P.) zones during artificial aging, which substantially enhances the yield strength. In general, the room temperature formability of magnesium alloy sheets shows negative correlations with yield strength; hence magnesium alloy sheets with relatively good formability all have low yield strength. In this talk, we overview our recent investigations on the development of bake-hardenable wrought magnesium alloys that can exhibit good room temperature formability with high yield strength and ductility for potential automotive body applications. Unique role of APT in the characterization of the G.P. zones will be presented.
