Kurzbeschreibung (Abstract)
High-pressure torsion (HPT) processed FeCr alloy with ultrafine-grained (UFG) microstructure was used to study the oxidation resistance and mechanical properties of the oxide scale. Thin and dense oxide scales formed on top of both coarse-grained and UFG FeCr samples after oxidation. Nanoindentation pop-in study suggested dislocation nucleation, crack formation, and oxide scale penetration events occurred during indentation. The results show that the oxide scales have excellent protection for the metallic substrate, and HPT process improves the oxidation resistance. Our work proves that HPT processing can improve both the mechanical properties and the high-temperature corrosion resistance for potential high-temperature applications.
