| Abstract: | The diagrams showing relations of formation free energy of the oxide, chloride and fluoride against temperature related to foundry of magnesium alloys were presented according to the thermo-dynamic data for magnesium alloying. On the physical and chemical background of melding and refining of magnesium alloys prepared by the flux treatment method, the thermodynamical principles were analyzed for the theoretic foundation of choosing flux rationally. The existing questions of preparing fluxes during melting, alloying and refining of the rare earth magnesium alloys were particularly analyzed, and the solution was presented. |
