Then, on the basis of above achieved constituent binary results, thermodynamic properties of 10 ternary liquid alioys (Cd-Bi-Pb, Cd-Pb-Sb, Cd-Pb-Sn, Mg-In-Cd, Zn-In- Cd, Cd-Bi-Sn, In-Bi-Pb, Sn-AgPb,Zn-In.Pb, Al-Cu-Zn), 3 quaternary ones (Cd-Bi-Pb-Sn, Zn-Sn-Cd-Bi, Zn-Sn-Cd-Pb) and 1 quinary. one (Zn-Sn-Pb-Cd-Bi) are predicted. For most of investigated multicomponent systems, the calculated activities are in good with the experimental ones, and in particular for multicompoment immiscible ones, the predicted results are satisfactory and exciting. At the same time, the comparison result between the three equations shows that Wilson equation and T-K-Wilson one are more stable than NRTL one, that maybe is because NRTL equation contains a third parameter, and so ,to some degree, Wilson model and T-K-Wilson model are superior to NRTL model. And also the comparison between local composition models and other models such as Pelton- Flengas?method, Krupkowski formalism, mass action concentration model and Hoch- Arpshofen model shows that local composition models are more convenient and credible.
在此基础之上应用局部组成型模型对10个三元液态合金(包括Cd-Bi-Pb、Cd-Pb-Sb、Cd-Pb-Sn、Mg-In-Cd、Zn-In-Cd、Cd-Bi-Sn、In-Bi-Pb、Sn-Ag-Pb、Zn-In-Pb、Al-Cu-Zn),3个四元液态合金(包括Cd-Bi-Pb-Sn、Zn-Sn-Cd-Bi、Zn-Sn-Cd-Pb)和1个五元液态合金(Zn-Sn-Pb-Cd-Bi)的活度进行了预测,预测效果良好,尤其对Zn-In-Pb系和Zn-Sn-Cd-Pb等多元液-液共存体系热力学性质的预测也取得了令人满意的结果;同时对三个方程的比较分析表明:Wilson方程和T-K-Wilson方程在多元系热力学性质的预测中表现稳定,而NRTL方程由于引入了物理意义不清楚的第三参数,使得其具有不确定性和不稳定性的特点,因此Wilson方程和T-K-Wilson方程较NRTL方程更为优越;此外对局部组成型模型与其它模型(如Pelton-Flengas方程、Krupkowski方程、作用浓度模型和Hoch-Arpshofen模型)的比较表明:局部组成型模型同样是优秀的,甚至在某些方面更为简便和可靠。
