dc.description.abstractThe N solubility in Fe–Cr–C–N melt was measured by the addition of Cr and C in liquid iron using the metal/gas equilibration technique at 1600 °C under a reduced N 2 partial pressure. Cr increased the N solubility by the attraction force between Cr and N, while C showed the opposite effect on N in liquid iron. The present experimental results were thermodynamically analyzed by Wagner's interaction parameter formalism. The existence of the simultaneous effect of Cr and C on the N solubility was confirmed, which was determined as the second-order cross-product parameter of Cr and C on N in liquid iron. This parameter set in the multicomponent Fe–Cr–C–N system can be used to predict the solubility limit of N in the degassing process of stainless steelmaking.en
