Additive manufacturing using tungsten, a brittle material, is difficult because of its high melting point, thermal conductivity, and oxidation tendency. In this study, pure tungsten parts with densities up to 18.53 g/cm3 (i.e., 96.0% the theoretical density) were fabricated by selective laser melting. order minimize balling effects, raw polyhedral powders underwent spheroidization process before consolidation. Compared powders, spherical showed increased absorptivity packing density, which...
Wire-feed electron beam additive manufacturing (EBAM) is a promising process for fabrication large-scale, fully dense and near net shape metallic components. However, limited knowledge available on the wire-feed EBAM of titanium alloys. In this work, Ti-5Al-2Sn-2Zr-4Mo-4Cr β alloy sample was fabricated by effect subtransus solution aging treatment microstructure evolution mechanical properties investigated. The results reveal that volume fraction primary α decrease dramatically from 48.6% to...
In order to improve the manufacturing efficiency of high-chromium superalloys, an innovative extreme high- speed laser metal deposition (EHLMD) process was used. The growth behavior precipitated phases, high-temperature mechanical properties, wear resistance, and corrosion resistance EHLMD K648 superalloy were investigated compared with conventional (CLMD) using transmission electron microscope, tensile tester, tester electrochemical workstation, respectively. results reveal that phase size...
A novel anticancer pro-prodrug (GMC-CAE-NO2) with diagnosis and therapy functions based on hypoxia photo sequential control was designed. It provides a platform for constructing theranostic pro-prodrugs to release active drugs controlled by hypoxic status UV illumination.
The grains, cellular structures, dislocation densities, and oxides in L-PBF 316LSS were systematically characterized. microstructure evolution mechanical properties closely associated with the scanning speed. sizes of grains significantly decreased increasing speed, while density remained relatively stable for speeds from 500-900 mm·s-1 increased when speed exceeded 900 mm·s-1. tensile samples exhibited obvious anisotropic properties, TD showed higher strength, attributed to strong <110>...
The strain-induced martensitic transformation (α′-martensite) and residual stress (RS) introduction in the gradient nanostructured (GNS) austenitic stainless steel have been extensively reported last three decades, however, their correlation is still unclear. Here, XRD, EBSD, ECCI TEM were used to study RS distribution martensite behaviors a GNS SS304 fabricated by ultrasonic surface nanocrystallization modification. We found non-linear relationship between magnitude of fraction...
The challenging wind conditions surrounding power transmission lines exacerbate the wear and corrosion of line fittings. Thermal diffusion galvanizing technology, a novel method for obtaining layers, significantly enhances resistance metal components, thereby extending their service life. Holding temperature plays critical role in determining performance thermally diffused zinc coating. In this study, we prepared coatings containing rare earth oxides on 35CrMo steel at various holding...
Multi-view classification based on evidence theory aims to enhance result reliability by effectively quantifying prediction uncertainty at the level, particularly when dealing with low-quality views. However, these methods face limitations in real-world applications due sensitivity of estimated view distribution, leading two main issues: 1) difficulty making clear judgments about whether trust predictions vague scores, and 2) potential negative impact integrating information from views...
A novel anticancer theranostic prodrug, FDU-DB-NO2, specifically activated by hypoxia for selective two-photon imaging status, real-time tracking drug release, and solid tumor therapy was designed. The devised prodrug consists of an floxuridine (FDU), a fluorescence dye precursor 4'-(diethylamino)-1,1'-biphenyl-2-carboxylate (DB), hypoxic trigger 4-nitrobenzyl group. In normal cells, FDU-DB-NO2 is "locked". Whereas in the "unlocked" results fluorescent 7-(diethylamino)coumarin (CM)...
High chromium superalloy K648, additive-manufactured by extreme high-speed laser metal deposition (EHLMD) process, was heat treated solution and then cooled at different cooling rates achieved conditions in this study. The investigation focused on the impact of (water-cooling (WC), air-cooling (AC) furnace-cooling (FC)) microstructure mechanical properties EHLMD K648 superalloy. As decrease, it observed that grain sizes, carbide, α-Cr grew larger. Simultaneously, carbides boundary evolved...
Cracking is a critical issue in the additive manufacturing of pure tungsten (W). To eliminate crack formation, it imperative to gain an in-depth understanding underlying mechanisms behind this process. In study, we systematically investigated behaviors single tracks, thin walls, and cubes fabricated using powder bed fusion–laser beam (PBF–LB) technology with nonrotational parallel-hatching scanning. The energy framework was employed elucidate mechanism formation. longitudinal cracks...
