摘要：The surface tensions, viscosities and molar volumes of liquid Ag-Bi-Sn alloys were calculated and presented in this paper. These physical properties have been estimated using the Kohler’s model for surface tension and molar volume and Seetharaman’s model for viscosity. The calculations were done along three selected sections with xSn/xBi = 1/2, 1/1 and 2/1 at different temperatures from 873 to 1273 K. The results show that up to 40 at. % Ag, no influence of the surface tension and no significant dependence on temperature has been noted. With increasing temperature the viscosity decreases smoothly. Both surface tension and viscosity increase significantly at high Ag-concentrations. The molar volume decreases linearly with increasing Ag-compositions and the calculated values are similar to those of additive molar volumes.
