FeCrAl alloys are leading candidates for accident-tolerant nuclear fuel claddings owing to their resistance to high temperature steam oxidation in accident scenarios. But low temperature steam oxidation of FeCrAl alloys, representative of top-of-core normal operation of boiling water reactors, must also be understood before these claddings can be safely deployed in reactors. This study evaluates FA-SMT (Fe-21Cr-5Al-3Mo) and PM-C26M (Fe-12Cr-6Al-2Mo) in 400 ºC steam for up to 1000 hr. The higher bulk Cr content in FA-SMT accelerates all reaction kinetics, leading to rapid growth of an outer Cr<sub>2</sub>O<sub>3</sub> layer, which then enables formation of a passivating inner Al<sub>2</sub>O<sub>3</sub> layer that hinders further oxidation. Meanwhile, Mo replaces Cr along grain boundaries, preventing additional Cr and Fe outward diffusion, and further hindering oxidation. By contrast, PM-C26M is more susceptible to steam oxidation as Mo remains in solid solution, allowing uncontrolled Fe oxidation. The beneficial effects of Mo in the presence of high Cr content may be considered a “fourth element effect” that can guide future design of high-strength, oxidation-resistant FeCrAl alloys.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"255 ","pages":"Article 113107"},"PeriodicalIF":7.4,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144288916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the influence of resin was systematically investigated together with a Weak organic acid (WOA) as activator component. For testing, specimens were exposed to constant humidity (95 %) and temperature cycling (40°C-65°C), while Electrochemical impedance spectroscopy (EIS) was used for monitoring moisture transport, and DC potentiostatic measurement as accelerated testing for triggering failures. Moisture absorption properties of coating were evaluated using gravimetric method. Hygroscopic nature of solder fluxes was carried out by EIS with changing humidity conditions. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FT-IR) were implemented for inspection of the coating/substrate interface and any potential chemical degradations.

This manifests as greater weight loss, a thicker inner oxide layer, more severe spallation, and pronounced local corrosion along grain boundaries, which will pose significant risks to the integrity of fuel claddings. To understand these phenomena, a comprehensive study combining advanced microscopic characterization and first-principles calculations was conducted.

Paradoxically, Fe<sub>2</sub>Nb-type Laves phase particles, provide localized protection to the underlying metal and significantly mitigate intergranular corrosion.
