The equilibrium of the reaction between oxygen in liquid Fe-Ni-Cr alloys and H2-H2O gas mixtures has been measured at 1600°C. Combining the present experimental data with the previous ones on the similar equilibrium in the systems of Fe-Ni, Fe-Cr and Ni-Cr alloys, the relationship between the apparent equilibrium constant and the ternary alloying composition was determined. From these, the isoactivity coefficient curves for oxygen were drawn in the ternary alloy field. Furthermore, the deviation of the Wagner’s relation from the present results on the activity coefficient of oxygen was examined. In order to keep the deviation below ±10%, the alloying compositions must be limited as follows;<BR>(This article is not displayable. Please see full text pdf.)
