Mg-Li based alloys, distinguished by their low density among structural metallic materials, emerge as pivotal candidates in ushering in the era of next-generation lightweight metals. Their notable drawbacks encompass poor room-temperature strength and creep resistance, prompting diverse efforts to enhance these aspects through microstructure control techniques, including heat treatment. The amelioration of mechanical properties in Mg-Li based alloys holds significant promise for advancing various industries, spanning aerospace, automotive, and biomaterials sectors. This review article provides an overview of endeavors aimed at improving the mechanical properties of Mg-Li based alloys, with a specific focus on alloying, heat treatment, and severe plastic deformation as strategies for microstructure control.
