Abstract
Based on the experimental data of phase equilibria and thermodynamic properties, the phase diagram of the Ag-Gd binary system was thermodynamically assessed by CALPHAD method. The solution phases including liquid, fcc (Ag), hcp (Gd) and bcc (Gd) were treated by simple substitutional model, of which the excess Gibbs energies were formulated with the Redlich-Kister polynomial. And three intermetallic compounds, AgGd, Ag2Gd and Ag51Gd14, were described as stoichiometric compounds. Finally, a set of self-consistent thermodynamic parameters formulating all the phases in the Ag-Gd binary system was obtained, which can reasonably reproduce all the experimental and thermodynamic data.
