Solubility of nitrogen in liquid iron, chromium and iron-chromium 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.
Results obtained are as follows:
1) Nitrogen solubilities measured in pure iron and chromium were,
log(wt% N)_Fe = -341/T-1.157
log(wt% N)_cr = 2860/T-.701 respectively.
2) Interaction parameter in liquid Fe-Cr alloy was,
e^cr_N=-126/T+.0231
3) Enthalpy change of nitrogen solubility in Fe-Cr alloys was,
△H^cr_N=5600-2430(wt% Cr) J/g-atom N
