Thermodynamic assessment of the Ag–Nd system

Abstract The Ag–Nd binary system has been assessed with CALPHAD approach based on experiment information of phase equilibria and thermodynamic properties. The excess Gibbs energies of the solution phases including liquid, BCC, FCC and DHCP were formulated with Redlich–Kister polynomial functions. The intermetallic compounds Ag 51 Nd 14 , α-Ag 2 Nd, β-Ag 2 Nd, and AgNd were treated as stoichiometric phases. Self-consistent thermodynamic parameters have been obtained and the calculated results agree well with most of experimental data.
