Abstract
All available thermodynamic and phase diagram data of the binary Al-Bi and Al-Sb systems and ternary Mg-Al-Bi and Mg-Al-Sb systems were critically evaluated, and all reliable data were used simultaneously to obtain the best set of the model parameters for each ternary system. The Modified Quasichemical Model used for the liquid solution shows a high predictive capacity for the ternary systems. The ternary liquid miscibility gaps in the Mg-Al-Bi and Mg-Al-Sb systems resulting from the ordering behaviour of the liquid solutions can be well reproduced with one additional ternary parameter. Using the optimized model parameters, the experimentally unexplored portions of the Mg-Al-Bi and Mg-Al-Sb ternary phase diagrams were more reasonably predicted. All calculations were performed using the FactSage thermochemical software package.
