A Review of Magnesium Alloys as Structure–Function Integrated Materials

Magnesium alloys have a significant advantage, lower density over the other structure materials; hence, they have been widely used in various fields such as transportation and aerospace. With the development of research and the enlargement of the research scope, more advantages have been revealed: excellent shielding efficiency, extraordinarily high damping capacity, as well as impressive thermal conductivity. Therefore, Mg alloys have the potential to be various functional materials, such as electromagnetic shielding material, damping material, and thermal conductive material. This review comprehensively summarizes the research progress and the up-to-date summary of Mg alloys as structure–function integrated materials in recent years. Solute atoms, heat treatment, deformation, secondary phase, and temperature, which have a significant influence on the properties of magnesium alloys, are highlighted. We expect this review to be helpful for those who are working on developing structure–function integrated materials with superior comprehensive performance.
