Abstract: Thermodynamic behavior of nitropen in Fe-Cr-Ni alloys at 1873K is discussed in the present study. The dependence of upon the content of Cr in Fe-Cr-Ni-N melt is expressed. The present authors' formalism[17] developed for describing thermodynamics of metallic multicomponent systems is successfully applied to the Fe-Cr-Ni-N quaternary system.

Key words: Fe-Cr-Ni alloy, nitropen, activity
