Fe-n-c phase diagram
WebCurrently available experimental data for the phase stability diagram of the Fe–N–C system, as well as isothermal sections of the ternary phase diagram, have been obtained from nitrocarburizing of iron powder in flowing NH 3 –H 2 –CO gas mixtures [6,7]. The water vapor content in the applied gas mixtures was, however, not provided, implying WebThe Fe-C phase diagram [1992Oka] is in the form of a double diagram, corresponding to the metastable equilib-rium with cementite (Fe 3 C) or the stable equilibrium with graphite. The peritectic formation of the solid solution (austenite) based on face-centered cubic (fcc) Fe is followed by the eutectic reaction, which yields austenite and cement-
