However, prolonged service exposure leads to γ'-Ni<sub>3</sub>(Al, Ti) precipitate coarsening, altering γ' morphology and lattice misfit (δ), which may compromise its oxidation resistance. This study addresses this gap by evaluating the oxidation response of IN740H with systematically varied γ' characteristics through thermal aging at 800 °C for 4 h to 10,000 h. Aging resulted in γ' precipitate growth from ∼18 nm (spherical) to ∼200 nm (cuboidal), with δ increasing from < 0.16 % to ∼0.52 %. Oxidation behavior was investigated via thermogravimetric analysis at 760°C for 100 h and long-term furnace tests at 760 °C for 1000 h. All samples formed a duplex oxide scale comprising an outer Cr<sub>2</sub>O<sub>3</sub> layer doped with TiO<sub>2</sub> and an inner Al<sub>2</sub>O<sub>3</sub> layer. Short-term testing revealed accelerated oxidation kinetics in samples with higher δ, indicating an inverse correlation between lattice misfit and oxidation resistance. In contrast, long-term exposure revealed a non-linear correlation, influenced by γ' coarsening. Samples with thermally stable, large cuboidal γ' precipitates exhibited superior oxidation resistance through sub-parabolic internal oxidation kinetics. In contrast, samples with finer γ' precipitates exhibited γ' instability, resulting in near-linear internal oxidation kinetics. This study underscores the critical role of γ' morphology and lattice misfit in determining the oxidation performance of IN740H under prolonged high-temperature exposure.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"257 ","pages":"Article 113268"},"PeriodicalIF":7.4,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144903519","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}

Here, we present a novel corrosion mitigation strategy for FeCrAl alloy by constructively leveraging the molten salt environment to induce a spinel protective layer on the metal surface. Porous alumina is initially engineered through selective anodization of FeCrAl, which facilitates Mg²⁺ incorporation and effectively relieves volumetric expansion stress during molten NaCl–MgCl₂ exposure. Consequently, the porous alumina is transformed into a compact and chemically robust MgAl₂O₄ spinel barrier. Corrosion testing at 700 °C for 700 h reveals nearly an order-of-magnitude less chromium depletion in the anodized FeCrAl (∼22 μm) compared with the bare alloy (∼171 μm). Comprehensive characterization, along with measurements of dissolved Cr concentration and mass loss, further support the enhanced corrosion resistance. This scalable strategy offers a viable pathway for long-term materials durability in next-generation nuclear power, concentrated solar power and thermal energy storage systems.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"256 ","pages":"Article 113262"},"PeriodicalIF":7.4,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144840725","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}
