Mixing properties of Cu–Mg liquid alloy

Abstract

Different modeling equations were used to predict the mixing behaviors of Cu–Mg liquid alloys at different temperatures. The thermodynamic and structural properties of the liquid alloy at 1100 K were calculated in the framework of the quasi-lattice test. The validity of the model parameters was obtained by comparing the obtained results with experimental values as well as other literature data. The mixing behaviors of the system were further predicted at different temperatures by assuming a linear temperature dependence of the interaction parameters. The surface and transport properties of the system were predicted at different temperatures using renovated Butler and Kaptay equations, respectively. Theoretical investigations showed that the mixing tendency of the system gradually decreased at higher temperatures.
