For a particle radius of 10 nm the eutectic point is found at a temperature of 193.9 °C and a composition of Sn-1.8 wt% Ag-0.7 wt% Cu. This shift toward the Sn-rich corner of the phase diagram is roughly consistent with the model proposed by Lee et al. [38] for binary alloys,...

a thermodynamic model is formulated for the Sn-Bi-Ag phase diagram. Thermodynamic functions for the various phases obtained by fitting measured data for the three constituent binary systems are extrapolated to the ternary system using the method of Muggianu. Modeling results are compared to preliminary...
