Abstract: Magnesium (Mg) alloy is the lightest metal material in practical application, and its structural parts are expected to be widely used in aerospace, rail transit, automobile, electronics and other lightweight fields. However, Mg alloy has the disadvantage of corrosion resistance, which seriously limits its wide application in the field of lightweight. Coating Mg alloy with good corrosion resistance aluminum (Al) alloy to form Mg-Al laminate can not only protect Mg alloy, but also play the advantages of high specific strength and specific stiffness of Mg alloy, good shock absorption and electromagnetic shielding performance. In this paper, the preparation methods and characteristics of Mg-Al laminates are reviewed, the microstructure evolution of component plates and layer interfaces in Mg-Al laminates and their influence on mechanical properties of the laminates are analyzed, and the innovative research results of our research group on stamping forming and deformation microscopic mechanism of Mg-Al laminates are introduced. How to prepare wider and thinner Mg-Al laminates with intermetallic compounds controllable at the interface is the focus of future research.
