 Abstract: We report the first observation of isothermal phase separation triggered by inwardly diffusing interstitial nitrogen atoms during nitriding of an equiatomic FeNiCo medium entropy alloy. Detailed microstructural characterization revealed a phase-separated microstructure within the nitrided region containing two FCC solid solution phases with one enriched in Fe and N while other enriched in Co and Ni. This demonstrates the potential utilization of interstitial N alloying to tailor the microstructure of multi-principal element alloys.
