Abstract
The initial oxidation behavior of Fe–24Cr–10Al (in at%) alloys with and without 0.006Zr or 0.06Zr during heating followed by isothermal oxidation for up to 30?min at 1000?°C was investigated by in situ high-temperature X-ray diffraction using synchrotron radiation and by STEM–EDS analysis. No apparent effect of Zr on the oxidation behavior, including the oxidation mass gain and scale microstructure, was observed during heating to approximately 1000?°C. The effect of Zr addition on the microstructure of oxide scale was first observed after formation of α-Al2O3 scale and inward growth of the inner Al2O3 layer. The effect of Zr was found to appear after Zr incorporation into the inner Al2O3 scale during its inward growth.
期刊介绍：
Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
