Abstract

Abstract: A critical evaluation and optimization of all available phase diagrams and thermodynamic data of the binary Sn–RE (RE=Gd, Tb, Dy, Ho, Er, Tm, Lu and Y) systems was conducted to obtain reliable thermodynamic functions of all the phases in the system. In particular, the thermodynamic properties of liquid phase were described using the Modified Quasichemical Model which takes into account the short range ordering of solution. The systematic analysis and the uncertainties in the Sn–RE systems were discussed. Highlights: The Sn–RE (RE=Gd, Tb, Dy, Ho, Er, Tm, Lu and Y) systems have been reviewed. The thermodynamic optimization of the Sn–RE systems have been performed. Systematic changes and similarities in the Sn–RE systems were found. The systematic approach resolved inconsistencies in the experimental data. The systematic approach was used to assess the unexplored phase diagrams.
