Abstract Scope |
The application of Mg alloys containing Ca, Sr and RE is expanding recently due to its good high temperature mechanical properties, formability and corrosion resistance. For the sustainable usage of these alloys, it is highly necessary to develop the proper recycling process of the Mg alloys. In the common melting recycling process of Mg alloys, molten salt of Na,K,Ca//Cl,F system is used to as refining flux. In the present study, the thermodynamic database for the Na,K,Mg,Ca,Sr,RE//Cl,F salt system was constructed and applied to the chemical equilibrium calculations between molten salts and liquid Mg alloys to investigate the refining recycling process of Mg alloys. |
