A thermodynamic description of the Fe-B-Cr system is developed 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-Cr and B-Cr, are taken from earlier assessments slightly modifying the Fe-B and B-Cr descriptions, and those of the ternary system are optimized in this study using experimental thermodynamic and phase equilibrium data from the literature. The solution phases are described using substitutional solution model. The borides are treated as stoichiometric or semi-stoichiometric phases and described with two-sublattice models.
