Abstract The activity of Fe was measured in liquid (Ni + Au + Fe) alloys (0 to 0.2 mole fraction of Fe) and solid (Ni + Fe) alloys (0 to 0.27 mole fraction of Fe) by individually equilibrating with iron silicate slag of known wüstite activity, and (CO2 + CO) gas mixture of known oxygen potential. For (Ni + Au + Fe) alloys, the activity of Fe showed negative deviations from ideality at most compositions studied, and for (Ni + Fe) alloys, marked negative deviations at all compositions studied. The latter result gave an activity of Ni, calculated from the Gibbs-Duhem equation, which was less ideal than reported previously.
