Calculation of the viscosity of the liquid ternary Ag–Au–Sn system

Abstract

Abstract The viscosity of the ternary Ag–Au–Sn system has been calculated using two different semi-empirical models which apply universal parameters valid for all metals. Experimental values of the integral enthalpy of mixing were used as inputs. The theoretical results are represented as iso-lines of the excess viscosity. Additional calculations based on a geometrical model fitted to the experimental viscosities of the binary systems were applied in order to discuss the physical significance of the results predicted for the ternary system.
