Measurements of AlN solubility were conducted in molten Fe-Cr-Ni alloys of different temperatures and compositions under a nitrogen partial pressure of 1 bar. This paper reports the results of an investigation on the composition dependence of AlN solubility in molten Fe-Cr-Ni alloys with a Cr to Ni mass ratio of 1:1, examined at intervals of 20 mass% Fe.
