Fe8 N4

Fe8N4 is an iron nitride compound that belongs to the family of transition metal nitrides, which are ceramic-like interstitial compounds combining iron with nitrogen. This material exists primarily in research and experimental contexts as a candidate for hard coatings and wear-resistant applications, where its high hardness and potential for improved mechanical properties over conventional iron-based materials make it of interest to materials scientists, though industrial adoption remains limited compared to more established nitride systems like TiN or CrN.
