•The Ni-Pr has been re-assessed using the latest experimental results.•The enthalpies of formation of NiPr and Ni5Pr measured by Kleppa were considered her for the first time.•The errors of related modeling presented in previous articles have been modified.•A self-consistent thermodynamic description of the Sm–Ni system was obtained.
Based on the available experimental data of phase equilibria and thermodynamic properties from the literature, the Ni-Pr binary system has been thermodynamically assessed using the CALPHAD method. The solution phases, Liquid, FCC_A1, DHCP and BCC_A2 were modeled as substitutional solution phases, for which the excess Gibbs energies were formulated with Redlich–Kister polynomials. All intermetallic phases were described as stoichiometric compounds. Subsequently, a set of self-consistent thermodynamic parameters describing various phases in this binary system has been obtained. The calculated results reproduce well the corresponding experimental data.
