Thermodynamic assessments of the Ag-Sm and Ag-Tb systems
The thermodynamic assessments of the Ag-Re(Re：Sm,Tb)binary systems were carried out by using the CALPHAD(Calculation of Phase Diagrams)method based on the experimental data including the thermodynamic properties and phase equilibria．The Gibbs free energies of the liquid,bee，fec，hop and Rhomb_C 19 phases were described by the subregular solution model with the Redlich-Kister equation，and the intermetallic compounds(Ag51Sm14，aAg2Sm,βag2Sm,AgSm,Ag51Tb14，Ag2Tb and AgTb phases)in these two binary systems were described by the sublatticc model．The thermodynamic parameters of each phase in the Ag-Re(Re：Sm,Tb)binary systems were obtained,and an agreement between the calculated results and experimental data was obtained in each binary system．
