What is the composition of ferro chromium nitride?

Ferro chromium nitride is mainly composed of CrN, Cr2N, Fe4N and other nitrides. In addition, the complex nitride (Cr, Fe) 2n (1-x) of ferrochrome may be formed. The main factors affecting the phase composition are nitriding medium and nitriding temperature. The stability of chromium nitride is higher than that of iron nitride.
