A thermodynamic description of the ternary Fe-B-Ni system is presented in the context of a new Fe-B-X (X = Cr, Ni, Mn, Si, Ti, V, C) database. The thermodynamic parameters of the binary sub-systems, Fe-B, Fe-Ni and B-Ni, are taken from earlier assessments slightly modifying the B-Ni description. Those of the Fe-B-Ni system are optimized in this study using experimental thermodynamic and phase equilibrium data from the literature. The solution phases of the system are described using the substitutional solution model and the borides are treated as stoichiometric or semi-stoichiometric phases of the (A,B)(p)C-q type described with two-sublattice model.
