N2 - Phase equilibria in the Fe-rich portion of the FeCNb ternary system were analyzed on the basis of experimental and thermodynamic data. The Gibbs energy of the Nb-carbide and solution phases was approximated by the two-sublattice model, being separated into the paramagnetic and ferromagnetic terms. In particular, the two phase equilibrium between austenite and cubic Nb-carbide was treated as a portion of the miscibility gap in the fcc FeCNb phase. The calculated phase boundary of austenite in equilibrium with the Nb-carbide showed a characteristic shape, as was the case in the FeCTi system.
