The alloy exhibits a yield stress of 462 MPa, an ultimate tensile strength of 1037 MPa, and a fracture strain of 31.8% at room temperature. Oxidation tests reveal that the oxide layer consists of an outermost oxide layer and a Cr2O3 layer at both 1000 and 1200 °C. The Cr2O3 layer formed at 1000 °C is dense and continuous, whereas it transitions from continuous to discontinuous as the temperature increases to 1200 °C. Localized peeling of the oxide layer is observed at 1200 °C due to the diminished protective effect of the Cr2O3 layer and the increased stress in the oxide layer caused by the formation of multiple complex oxides. Grinding experiments indicate that both the grinding force and surface roughness increase as the load increases. Additionally, energy-dispersive X-ray spectroscopy results show that the oxygen content of particles at a 120 N is higher than at 60 and 90 N, suggesting an elevated grinding temperature at 120 N, which leads to the formation of bonded convex particles.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 4","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nano-oxide particles in the ODS-NFA tube stabilize the ultrafine fibrous grains and result in delayed recrystallization at 1200 °C. Hardness measurements and electron backscatter diffraction quantify the recrystallization kinetics, grain size, and texture evolution of both alloys during recrystallization. The recrystallization mechanism of FeCrAl alloy is grain boundaries and Laves precipitates stimulate nucleation, while the recrystallization of ODS-NFA is controlled by nanoparticle dissolution and reprecipitation. Completely recrystallized FeCrAl alloy shows ≈20 μm grains and ODS-NFA shows ≈10 μm equiaxed grains.

Inconel 718 (IN718) alloys with varying Pt content were prepared and subjected to isothermal oxidation tests. The results demonstrate that Pt significantly enhances the oxidation resistance of IN718, as evidenced by reduced weight gain, thinner oxide layers, and smaller oxide particles. Pt addition also increases the activation energy for both initial interface oxidation and ion diffusion during long-term oxidation. Furthermore, Pt promotes the formation of a Cr2O3 layer while suppressing the formation of other undesirable oxides, resulting in a more cohesive and stable oxide layer. The improved oxidation resistance is attributed to two key factors: during the initial oxidation stage, Pt, as a noble element, reduces the activity of the primary oxide-forming element Cr to oxidative environments, thereby lowering its susceptibility to initial oxidation at the metal–oxidant interface. During long-term oxidation, Pt preferentially substitutes for Ni in major phases such as γ-Ni(Cr,Fe) and γ′-Ni3(Al,Ti), locally increasing the Cr composition. This promotes Cr oxidation, effectively suppressing the oxidation of Ni or Fe. These findings suggest that Pt addition is a promising approach for enhancing oxidation resistance in alloy design.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 2","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The predictive models of strength-parameters, porosity-parameters, and strength-porosity are established and validated.

The wettability and corrosion resistance of the coating were studied by contact angle (CA) measuring instrument and electrochemical workstation. Meanwhile, the durability of the coating was evaluated by sandpaper abrasion, tape peeling and immersion test. The results showed that the hydrophobic Mg–Al LDH coating can be successfully prepared on the surface of MAO ceramic layer by one-step hydrothermal treatment with alkaline aluminum nitrate solution containing sodium laurate. The hydrophobic Mg–Al LDH coating sealed the inherent defects of MAO ceramic coating, resulting in significantly improved corrosion resistance. With the extension of sandpaper abrasion distance, tape peeling times, and immersion time, the CA of the coating shows a downward trend, and the coating gradually changed from hydrophobic to hydrophilic.

Varying the aging temperatures leads to the formation of lamellar structures consisting of face-centered cubic (FCC) and body-centered cubic phases, which significantly influence the mechanical properties of the alloy. The aging treatments reveal an inverse relationship between temperature and microhardness, with values decreasing from 890 to 700 HV as the temperature rises from 550 to 650 °C. Despite this reduction, the alloy retains a high hardness level, suitable for wear-resistant applications. The best wear resistance is observed at 550 °C, with a wear rate as low as 8.45 ± 1.6 × 10−5 mm3 N−1 m−1. This is attributed to stacking faults and dislocations within the FCC lamellae, which enhance resistance to dislocation glide.
