  • METHODS OF FORMING MAGNESIUM-BASED ALLOYS HAVING A BIMODAL MICROSTRUCTURE AND MAGNESIUM-BASED ALLOY COMPONENTS MADE THEREFROM
    Publication number: 20230383385
    Abstract: Methods of making magnesium-based alloy components are provided. A preform of a magnesium-based alloy having a plurality of zirconium-rich domains distributed in a magnesium-alloy matrix is subjected to a temperature of ? about 360° C. and a deformation process that facilitates selective dynamic recrystallization to create a bimodal microstructure in the magnesium-based alloy component having a plurality of un-recrystallized regions distributed in a matrix comprising dynamically recrystallized grains. The magnesium-based alloy includes zinc (Zn) at ? about 2 to ? about 4 wt. % of the magnesium-based alloy, zirconium (Zr) at ? about 0.62 wt. % to ? about 1 wt. % of the magnesium-based alloy, total impurities at ? about 0.1 wt. % of the magnesium-based alloy, and a balance of magnesium (Mg). Hot-formed magnesium-based alloy components formed from such methods are also contemplated, including automotive components.
