In this study, the corrosion response of Al-Mg-Sc-Zr alloy produced by selective laser-melting in marine atmospheric environments with different Cl− concentrations was studied electrochemical and immersion. Microstructural observations showed microstructural Al-Mg- Sc -Zr featured a double grain microstructure, making up coarse fine area. TEM that some white precipitates enriched Zr were dispersed samples. The potentiodynamic polarization test indicated increasing concentration led to...
The formation of intermetallic compounds (IMCs) is a primary factor that affects the welding joint between dissimilar materials. In this study, experiments were performed using Al/Mg friction stir (FSW) and ultrasonic vibration enhanced FSW (UVeFSW) with varying thicknesses Sn interlayer. Detailed characterization tests conducted to explore effect interlayer or without on weld surface morphology, macro-micro structure, generation IMCs, tensile strength. study discusses coupled provides ideas...
The combination of a sol–gel precursor approach and microwave heating leads to hitherto unknown MAX phase Cr 2 GaC 1− x N . Magnetic measurements reveal that the susceptibility depends on nitrogen amount X-site.
Abstract To study the transportation of magnetic flux from large to small scales in protostellar sources, we analyzed Nobeyama 45 m N 2 H + (1–0), JCMT 850 μ polarization, and Atacama Large Millimeter/submillimeter Array (ALMA) C 18 O (2–1) 1.3 0.8 mm (polarized) continuum data Class 0 protostar HH 211. The field strength dense core on a 0.1 pc scale was estimated with single-dish line polarization using Davis–Chandrasekhar–Fermi method, that envelope 600 au force balance between gravity...
Abstract The KF110–Si 3 N 4 –La 2 O –Cu composite coatings were fabricated on TA2 by a laser cladding (LC). Microstructure, elemental distribution, high temperature oxidation, and wear resistance investigated. Research results showed that the nanocrystalline phases (NPs) amorphous (APs) formed due to existence of short atomic radius elements/fast cooling rate during an LC process; uniform distributed NPs with interface energy produced addition Cu, enhancing coating. Lattice distortions...
The process of grain refinement during welding significantly influences both the final microstructure and performance weld joint. In present work, merits acoustic addition in conventional Frictions Stir Welding (FSW) were evaluated for joining dissimilar Al/Mg alloys. To capture near “in situ” structure around exit hole, an “emergency stop” followed by rapid cooling using liquid nitrogen was employed. Electron Backscatter Diffraction analysis utilized to characterize examine evolution within...
Wire-arc additive manufacturing (WAAM) has fully empowered the design and of metals with its unparalleled efficiency flexibility. However, process relatively poor shape control capabilities, often requiring machining post-processing. This study explores a tungsten inert gas arc remelting (TIGAR) to improve surface flatness WAAM components at low cost significantly reduce waste (up 76%), which is crucial for sustainable development process. The extent improvement under different currents was...
Abstract To study the stress rupture properties of A286 alloy in high temperature service environment, tests at different ranges and levels were carried out. Moreover, Larson-Miller Parameter (LMP) for predicting life was established as LMP = ( T + 273)(log t r C ) × 10 −3 , 22.3. The fracture morphology microstructure evolution specimens observed by scanning electron microscopy. results show that 700 °C–750 °C/150–400 MPa, precipitation closely arranged cellular η phase coarse MC grain...
Underwater wet flux-cored arc welding(FCAW) has great potential prospects of wide application in ocean engineering due to its easiness automation and high weld quality.However,the thermal process underwater welding is more complicated:the energy distribution concentrated high-pressure environment underwater,the convection heat transfer coefficient the weldment under water much larger than that air.This study focuses on establishing numerical model for analyzing temperature field FCAW by...
