PROBLEM TO BE SOLVED: To provide a method capable of elucidating a strengthening mechanism of an Mg-Li alloy including a third element such as Zn and Al and appropriately evaluating the Mg-Li alloy. SOLUTION: The evaluation method of Mg-Li alloys formed by containing at least, Mg, Li, and a third element includes: obtaining a HAADF-STEM image of the Mg-Li alloy by a high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), and confirming the structure of the Mg-Li alloy and an eccentrically distributed state of heavy/light elements (Zn and Li) in the Mg-Li alloy.
