Application of an optimized geometrical model in predicting the physicochemical properties of Sn-based alloys

Geometrical model has been widely used in the property prediction of melts, where three "representative points " on binary systems are selected for the calculation of ternary systems. In this paper, an optimized method with "representative regions " of binary systems is first proposed for the calculation based on geometrical model. The "weight probability " of all the points within the "representative region " is quantified by the Gaussian distribution density function. The optimized geometrical model (OGM) is verified in predicting the physicochemical properties of Sn-based ternary alloys, and good accordance was obtained between the calculated results and experimental values.
