Density functional theory was employed to investigate the structure and properties of Ni/Cr2O3 Ni/Al2O3/Cr2O3. The O-terminated Ni(1 1 1)/Cr2O3(0 0 1) interface firstly found be most stable configuration. Based on this construction, effects Al diffusion at were further studied. results total energies indicate that atoms originating from Ni slab prefer diffuse into Cr2O3 through interface, resulting in formation alumina interface. Due presence atoms, there an amazing increase work adhesion,...
To reduce the precipitation of σ phases and to improve hot workability S31254 steels, boron has been added into composition a concentration 40 ppm. The behavior was investigated before after addition in different alloys during compression deformation, nose temperature at 950 °C phase dissolution 1074 were selected as measurement temperature. result showed that more precipitated grain boundary alloys, compared boron-added alloy. Meanwhile, ppm obviously prevented from austenitic matrix, it...
The effects of boron on the microstructure and intergranular corrosion behavior UNS S31254 (S31254) austenitic stainless steels were investigated. sensitivity to in samples was determined by an altered double loop electrochemical potentiokinetic reactivation method. characterization showed that only precipitated sigma (σ, Fe-Cr-Mo-Ni) phases during aging process, but addition decreased amount σ phase precipitation, reduced size phases, promoted formation small Laves at grain boundaries. lead...
High levels of antibiotic accumulation and the difficulty degradation can have serious consequences for environment and, therefore, require urgent attention. To solve this problem, a synergistic Er Cd ion-codoped Bi
Precipitation in super-austenitic stainless steels will significantly affect their corrosion resistance and hot workability. The effects of Cr Mo on precipitation behaviors were mainly achieved by affecting the driving force for precipitation, especially has a more substantial promotion effect formation σ phase than Cr. In present study, B addition to S31254 shows an excellent ability inhibit precipitation. was investigated microstructure characterization theoretical calculations....
We utilized a first-principle density functional theory for comprehensive analysis of CsPbX3 (X = F, Cl, Br, I) to explore its physical and chemical properties, including mechanical behavior, electronic structure optical properties. Calculations show that all four materials have good stability, modulus elasticity, hardness wear resistance. Additionally, demonstrates vertical electron leap serves as semiconductor material with direct band gaps 3.600 eV, 3.111 2.538 eV 2.085 eV. In examining...
The second phases in the S31254 super austenitic stainless steel is easily precipitated, and solution treatment plays an important role on microstructure performance. In this work, performed at 1180, 1200, 1220 °C for 1, 2, 4 h, respectively. Given grain size precipitation of phase, 1200 h or 2 may be suitable as solid‐solution parameters. corrosion resistance impact toughness after are further investigated by means microstructural analysis electrochemical experiments. sample where no phase...
In austenitic steels, the co-segregation of C and Cr at grain boundaries can result in formation Cr23C6. However, addition B to steels effectively reduce amount Cr23C6 formed inhibit its ripening experiments, simultaneously transforming it into Cr23(BC)6. Therefore, effect on Σ5(210), Σ9(221) Σ11(113) was investigated using density functional theory. The results indicate that B, C, all tend segregate three boundaries, with showing a stronger segregation tendency. Furthermore, short distances...
Aiming to address the Mo volatilization problem of super-austenitic stainless steel at high temperature, S31254 containing B and rare earth element Y with oxidation resistance was designed. It observed that a synergy + can promote formation dense Cr2O3 layer 1050 1100 °C, making MoO3 difficult. While oxide layers 0B sample from top bottom were divided into four layers: Fe-rich layer, Cr–Mn–Ni spinel (loose porous), thus undense in hardly inhibit volatilization, especially °C. In addition,...
