Thermodynamic Description Of Ternary Fe-B-X Systems. Part 2: Fe-B-Ni

Abstract 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)pCq type described with two-sublattice model.

Thermodynamic description of the ternary Cu-Mg-Sn system at its Cu-Mg side is presented. The thermodynamic parameters of the binary sub-systems, Cu-Mg, Cu-Sn and Mg-Sn, are taken from the earlier SGTE-based assessments (modifying the Mg-Sn description slightly) and those of the Cu-Mg-Si system are optimized in this study using the experimental thermodynamic and phase equilibrium data. The solution phases of the systems are described with the substitutional solution model and the intermetallic Cu2Mg compound (Laves C15), treated as simple semi-stoichiometric phases of the (A,B)pCq type, is described with the twosublattice model. The present ternary description is valid for tin contents up to 45 wt% (xSn?0.30).

Abstract A thermodynamic optimization of the ternary Fe-B-Mn system is presented. The thermodynamic parameters of the binary sub-systems, Fe-Mn, Fe-B and B-Mn, are taken from earlier assessments slightly modifying the B-Mn system description. The thermodynamic parameters of the Fe-B-Mn system are optimized in this study using literature experimental thermodynamic and phase equilibrium data. 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)pCq type described with the two-sublattice models.
