Abstract

Magnesium alloys exhibit poor room-temperature formability due to their hexagonal close-packed (HCP) structure, which limits their widespread application. Superplastic forming offers an effective solution, enabling elongations typically from ∼400% to over 1000%, and exceeding 3000% under optimized severe plastic deformation (SPD) conditions. This review provides a critical and systematic assessment of the microstructural design principles governing superplasticity, emphasizing the roles of fine equiaxed grains (
