The results of Monte Carlo simulation disclose that in large range of nitrogen fugacity the solubility of the interstitial nitrogen in αFe obeys Sievert's law. This range is much larger than that in γFe-N system. The results also show that in order to get the same level of interstitial nitrogen solubility in αFe-N system during solid state nitride, larger nitrogen fugacity is needed at the lower temperature.
