The low-density magnesium (Mg) alloys are attractive for the application in aerospace, transportation and other weight-saving-required fields. Additionally, the magnesium alloys also have some unique properties, such as good biocompatibility and biodegradability, high damping capacity, good magnetic shielding properties and etc., which can provide plus functional properties for the structural applications. Therefore, the green, eco-friendly Mg alloys attract a new round of attentions under the zero-CO2 Policy.

Consequently, there are many studies on these aspects and the effects of alloying elements are always the most basic study points. It is noteworthy, as being Mg alloys, the most important phase is inevitably the primary Mg phase. 

In this work, the thermodynamics and kinetics of Mg-rich systems are studied combining experiments and calculations. These fundamental information are applied for the magnesium alloy design and processing design. The purification methods of Mg alloys are developed. Based on the multi-solute behavior, the basic alloy design for the structural and functional integrated Mg-alloys is proposed and applied. Series high performance Mg alloys have been developed.
