Abstract:
This presentation will first develop an overall understanding of the role of grain size in oxidation of Fe-Cr microcrystalline alloys. Based on this understanding for nanocrystalline grain size, the mechanistic role of nanocrystalline alloy grain size in oxidation resistance of Fe-Cr alloys will be discussed. An elaborate description of the author’s own hypothesis that nanocrystalline structure can impart extraordinary oxidation resistance and the validation of this hypothesis will be presented. The data to be presented will include the results establishing that an Fe-Cr nanocrystalline alloy with only 10wt% Cr can provide as much oxidation resistance as an Fe-20Cr alloy, suggesting possibility of Fe-Cr alloys with the necessary corrosion resistance at much lower Cr contents.
