Constructing surface coatings is an effective way to improve the corrosion resistance and biocompatibility of magnesium alloy bioabsorbable implants. In this present work, a titanium oxide coating with thickness about 400 nm was successfully prepared on MgZn via facile magnetron sputtering route. The features were characterized using scanning electron microscopy (SEM), atomic force (AFM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS), contact angle method. behavior evaluated....
Abstract A newly developed large-volume potassium-doped tungsten (W–K) plate with a thickness of 15 mm and weight 25 kg by powder metallurgy plus hot rolling was prepared to meet the requirements International Thermonuclear Experimental Reactor (ITER) in engineering application. In order clarify effect K doping on thermal shock performance W–K alloy, transient tests single-pulse duration 1 ms for 100 shots at room temperature were performed. The absorbed power density is set 0.33, 0.44, 0.55...
The hot deformation behaviors of a new Ti-6Al-2Nb-2Zr-0.4B titanium alloy in the strain rate range 0.01–10.0 s−1 and temperature 850–1060 °C were evaluated using compressing testing on Gleeble-3800 simulator at 60% degree. flow stress characteristics analyzed according to true stress–strain curve. constitutive equation was established describe change with rate. thermal activation energy Q equal 551.7 kJ/mol. ε ˙=e54.41[sinh (0.01σ)]2.35exp(−551.7/RT). On basis dynamic material model...
In this study, a 25 kg potassium doped tungsten (KW) plate dispersed K bubbles was prepared by hot rolling firstly. order to evaluate the mechanical properties of KW after irradiation, synergistic irradiation Fe11+ ion, He and D plasmas were performed on pure (PW). 3.5-MeV ion used simulate displacement damage induced neutrons. The total fluence temperature 5.31 × 1014 m−2 for 0.5 displacements per atom (dpa) 400 K, respectively. Positron annihilation Doppler broadening spectrometry (PA-DBS)...
Ti–6Al–2Nb–2Zr–0.4B alloy plates were welded using tungsten inert gas welding with a new matching wire, and the chemical composition, microstructure, mechanical properties of defect-free joint investigated. Furthermore, influence mechanism TiB phase on was analyzed. The results indicated that B content in weld metal is only 0.0145% trace phase. A large amount phases precipitate fusion zone aggregate at grain boundary. heat-affected are distributed diffusely. microhardness (295 HV) lowest,...
Abstract A large-size potassium-doped tungsten (KW) plate with a thickness of 15 mm was fabricated via powder metallurgy technology and hot rolling. In order to appraise the irradiation resistance KW, surface deuterium (D) blistering D retention were studied on Fe 11+ pre-damaged (0, 0.05 0.5 dpa) KW pure (PW), which exposed ∼60 eV ∼5 × 10 21 m −2 s −1 plasmas at 500 K fluence ∼5.76 25 . The results indicate that alloy can better inhibit generation vacancy defects after ion damage compared...
A developed tungsten (W) grade was prepared by powder metallurgy technology plus multi-step low-temperature rolling. The relative density, thermal conductivity, microstructure, tensile properties of original and high-temperature annealed states, micro-hardness transient shock resistance were characterized. results test with a strain rate 2 × 10-4 s−1 show that the ductile–brittle transition temperature (DBTT) rolled-W in recrystallized state are 150–200 °C 250–300 °C, respectively. presents...
