The oxidation products are identified in situ and the difference method yields curves Y(T) showing the global changes. These curves were calibrated to the microscopically measured and thickness of the oxide layer obtaining the growth x(T). A calculated curve including the Arrhenius relation was fitted to the x(T) curve yielding activation energy and values of the oxidation rate constant as a function of temperature.enArmco ironcorrosionhigh temperature oxidationin situ investigationnon-isothermal kineticsoxidation productx-ray diffraction660541journal article
