A thick plate of Ti–6Al–2Zr–2Sn–3Mo–1.5Cr–2Nb (TC21) damage-tolerant alloy was electron-beam welded and the joint treated via solution aging. The microstructural characterizations mechanical properties welding solution-aging states were also investigated. results indicated that in state, fusion zone (FZ) is composed grain boundary α, martensite α′, residual β phases. heat-affected (HAZ) consists mainly primary microhardness value FZ higher than HAZ base metal (BM), hardness from to BM...
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...
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 The effect of the applied tensile stress on exfoliation corrosion 7075‐T6 alloy in EXCO solution has been studied. Electrochemistry Impedance Spectroscopy (EIS), Scanning Electron Microscope (SEM) and optical microscope techniques were used to characterize initiation propagation (EC) under different levels. Two equivalent circuit models developed fit EIS data stages EC according their corresponding physicochemical properties respectively. correlation between characteristics...
The different thickness (Fe/Pd)n coatings were prepared by vacuum ion plating technology on a pure Ti substrate. magnetized using an MC-4000 high-pressure magnetizing machine. Then, the effect of coating magnetic properties was studied. surface and section morphology, composition, phase structure, properties, biocompatibility studied scanning electron microscopy, X-ray diffraction, energy-dispersive spectroscopy, CCTC-1 digital flux field measurement. results showed that granular, smooth,...
In this paper, a simple method to fulfill the ideal microstructural design of particle reinforced tungsten (W) alloys with promising mechanical properties is presented. W-0.5 wt.% TiC powders core-shell (TiC/W) structure are prepared by ball-milling and controlled hydrogen reduction processes. TEM observation demonstrates that nano particles well coated tungsten. The W-TiC sintered spark plasma sintering (SPS) under 1600 °C. microstructures characterized FESEM TEM. It found W-0.5TiC obtain...
Powder Bed Fusion (PBF) not only enables the fabrication of metal parts with complex geometries in near-net-shape, but also offers potential to tailor microstructure and, consequently, mechanical properties final product. In this contribution, we present our in-house developed simulation software SAMPLE3D (Simulation Additive Manufacturing on scale using a Laser or Electron beam 3D), which is designed specifically for simulating grain structure evolution during PBF processes. The core...
