Solubility of nitrogen in liquid iron, iron-chromium and iron-nickel alloys has been measured by the sampling method under 1 atm N₂pressure. Experiments were carried out at the temperature range of 1829-2205K and at the composition range of 0-30.2% Cr and 0-40.0% Ni.
Results obtained are as follows:
1) Nitrogen solubility measured in pure iron was, log (wt % N)_Fe=-341/T-1.157.
2) Interaction parameters in liquid Fe-Cr and Fe-Ni alloys were,
3) Enthalpy change of nitrogen solubility in Fe-Cr and Fe-Ni slloys were,
