Abstract: Thekey parameters of the thermodynamic models of the molten alloyswere calculated in artificial fish swarm algorithm(AFSA) to simplify and improve the data-processing accuracy of the experimental results in conventional methods.The molten alloys commonly involved in vacuum distillation,including the Cd-Zn(strong positive deviation),Ag-Pb(weak positive deviation),Bi-Tl(strong negative deviation),Pb-Sb(weak negative deviation) and In-Sn(co-existed deviation),were selected for the analysis in AFSA and the major parameters,such as Ωij,of the molecular interaction volume model(MIVM),Bij and Bij of the regular solution model,were numerically calculated with self-developed Java software by minimizing the mean deviation S between the analytically predicted and literature reported activity coefficients.The preliminary results show that AFSA considerably improves the prediction precision of Ωij,Bij and Bji,widening their applications in binary alloy systems.
