dc.description.abstract	Internal oxidation was employed to determine oxygen permeability in the Fe-Ni system between 1000 & DEG;C and 1150 & DEG;C at the oxygen partial pressures of Fe/FeO equilibrium. Fe-Ni-Cr alloys were exposed to environments with and without carbon to assess the influence of dissolved carbon on oxygen permeability. A detailed examination of the classical diffusion model for internal oxidation allowed increased accuracy of the permeability measurement. Oxygen permeability decreased nonlinearly with Ni content in the alloy, driven by a decrease in oxygen solubility. No carbon effect was detected in Ni-containing alloys.
