Abstract
A new iron oxide is found to form on the surface of a Cu–0.2 at.% Fe alloy foil between 843 and 919 K under oxygen partial pressures of less than 10−5 Torr. The growth rate is controlled by the diffusion of dissolved Fe to the surface. The 57 Fe Mössbauer resonance of the oxide consists of two quadrupole pairs at 298 K both indicative of the Fe2+ oxidation state. A phase transition occurs in the oxide below 298 K such that only a single quadrupole pair remains at 76 K.This publication has 4 references indexed in Scilit:
