Phase equilibria in Al-Ca-Li system: a thermodynamic description

Abstract

Relations of equilibrium phases in the Al-Ca-Li system were calculated by means of the CALPHAD (calculation of phase diagram) method. The reported thermodynamic model parameters for all the constituent binary systems were directly used in the present calculation. A novel thermodynamic description for the three ternary intermetallic compounds(τ ₁, τ ₂ and τ ₃) was made on the basis of experimental phase equilibria in the Al-Ca-Li system. Comparison between the calculated and experimental phase equilibria shows that we have successfully derived a set of self-consistent thermodynamic parameters for the Al-Ca-Li system. These parameters were then used for the prediction of the selected isothermal and isopleth sections and projected liquidus surface of this ternary system over the entire composition range.
