Abstract

Abstract The purpose of present study was to obtain information on the solubility of components of structural materials in liquid Sn-20Li alloy in the temperature range of practical interest. To solve this problem, a thermodynamic simulation method was used, which included the following steps: (1) selection of models for the Gibbs energy functions; (2) selection and evaluation of input data; (3) optimization of model parameters; (4) calculations and comparisons. Using information on the excess Gibbs energies for the liquid phase in the form of Redlich-Kister polynomial expansions, for the corresponding binary systems, the temperature dependencies of solubility of nickel, iron, chromium, molybdenum and tungsten in the liquid Sn-20Li are calculated. The results of the calculations are in satisfactory agreement with the experimental data known from the literature.
