Thermodynamic modeling of the Ca–Li–Na system

The binary Ca–Na and Li–Na systems were modeled by computational thermodynamics using the Calphad method. Self-consistent thermodynamic parameters of the binary systems were obtained. Combined with the Ca–Li system modeling in the literature, the phase equilibria of the Ca–Li–Na system were calculated. Isothermal and isopleth sections of the ternary system and the projection of the liquidus surface were presented. This ternary system will be included in the study of the impurity effects on processing of aluminum alloys.
