Abstract

The model of an ideally associated mixture has been applied to describe equilibria in the Fe-rich corner of the ternary Fe-Al-N system. It has been found that when the molar ratio of aluminum to nitrogen is higher than 2.5, more than 90% of N is complexed into AlN molecules (associates) at a temperature of 1873 K. The phase boundaries between liquid iron and N2 gas on the one hand, and between liquid iron and solid AlN on the other hand have been determined. The solubility of N2 gas increases with increasing concentration of aluminum in the liquid. The concentration dependence of the solubility of AlN considerably differs from that predicted by the concept of the `solubility product', due to the strong complex (AlN) formation in the system.
