Abstract
The thermochemical and phase-equilibrium data of the In-Pd binary system were critically reviewed. A self-consistent thermodynamic description of the system was obtained using the CALPHAD approach. Eight intermetallic compounds were considered in the system. The InPd(B2) compound was described by a two-sublattice model. The compounds In7Pd3, In3Pd2, In3Pd5, αInPd2, and αInPd3, with negligible homogeneity ranges, were modeled as stoichiometric compounds. βInPd2 and βInPd3 were treated as stoichiometric compounds due to a lack of experimental information. Model calculations agreed satisfactorily with most existing experimental data. The thermodynamic factor for the InPd(B2) compound was also predicted based on the present thermodynamic description.
