چکیده انگلیسی
Critical evaluations and thermodynamic modeling of the Ag-(Ca, Li, and Zn) and Ca-(In, Li) binary systems are presented. Thermodynamic optimization of the Ag-Li binary system was carried out in the present work at first. Thermodynamic re-optimizations of the Ag-Ca, Ag-Zn, Ca-In and Ca-Li binary systems were carried out in the present work, which presents improvements in comparison with previous works. The Modified Quasichemical Model in the Pair Approximation (MQMPA) was used for the liquid solution; this model is particularly suited for liquid which exhibits a high degree of short-range order. The intermetallic compounds are modeled with the Compound Energy Formalism (CEF), and terminal solid solutions are modeled with Bragg-Williams model (BWM) with sub-regular solution approximation. All available and reliable experimental data are reproduced within experimental error limits. A self-consistent thermodynamic database was constructed for the Ag-(Ca, Li, and Zn) and Ca-(In, Li) binary systems, which as a part of the thermodynamic database of the Mg-X (X: Ag, Ca, In, Li, Na, Sn, Sr, and Zn) multi-component system shall facilitate the development of Mg alloys for practical industrial purposes.
