When nitrogen gas is reacted on melts of binary Fe-Al alloys under a pressure of one atmosphere, a part of the nitrogen enters the melts, (1) as non-metallic inclusions in the form of AlN compound, while the other part becomes (2) interstitially dissolved nitrogen in its atomic state. We measured the quantity of nitrogen in the two above states separately with respect to samples of Fe-Al alloys of various compositions. In particular, we investigated the relation between the quantity of the interstitially dissolved nitrogen and the aluminium content of the various samples, and arrived at important results suggesting a basic relation in the elimination of nitrogen in iron. melt at variance with the theory accepted hitherto. A statistico-thermodynamical study of the results gave satisfactory answers.
