Abstract
The solubility of nitrogen in molten iron and molten iron alloys has been analysed on the basis of statistical thermodynamics developed for the analysis of very dilute interstitial solutions in which solute–solute interaction is assumed to be negligible. Nitrogen atoms in molten iron appear to be stabilized to an extent similar to those in α-iron. The present analysis also shows that substitutional alloying elements vanadium and chromium may function as trapping sites for nitrogen atoms in molten iron. The importance of an appropriate statistical model is pointed out for this type of analysis.
