Comprehensive insights into recent innovations: Magnesium-inclusive high-entropy alloys

This review focuses on thermodynamic and physical parameters, synthesis methods, and reported phases of Magnesium (Mg) containing high-entropy alloys (HEAs). Statistical data of publications concerning Mg-containing HEAs were collected and analyzed. Data on the chemical elements included in Mg-containing HEAs, their theoretical end experimental densities, thermodynamic parameters, physical parameters, fabricated techniques and reported phases were also collected and discussed. On the basis of this information, a new classification for HEAs was proposed. It is also shown that the existing thermodynamic parameters cannot accurately predict the formation of a single phase solid solution for Mg-containing HEAs. The physical parameters of Mg-containing HEAs are within a wide range, and most of the synthesized Mg-containing HEAs have a complex multiphase structure.
