The interaction coefficients of Fe-N, Fe-C and C-Nwere obtained and the phase boundaries of single-phase ε-and γ_1-fields were subse-quently calculated. The results show that the γ_1-region of Naumann and LangescheidFe-C-N ternary phase diagram is correct, but the ε-region requires revision. Calcu-lation give an evidence that most of the experimental data on the ε-phase report-ed by Wells and Bell appears reasonable. Calculations taking graphite as a standaredstate confirms the above conclusions.
