Estimation of viscosity of ternary-metallic melts

A new model, based on Seetharaman’s viscosity model and Chou’s geometric-thermodynamic model, to predict the viscosity of ternary-metallic melts has been established. The viscosities of Ag-Au-Cu and Ag-Sn-Cu systems have been calculated with the present model, and the results are consistent with the experimental data. The viscosities of Au-Ni-Cu, Fe-Ni-Cu, Al-Sn-Cu, and In-Sn-Bi systems have also been predicted by the present model.
