Abstract When face-centered cubic (FCC) metals and alloys with low stacking fault energy (SFE) are irradiated by high-energy particles or deformed at high speed, tetrahedra (SFTs), which a type of vacancy cluster defect, often formed. Therefore, SFTs were expected to form in the CoCrFeMnNi equiatomic high-entropy alloy (HEA). However, no SFT was observed HEA high-speed plastic deformation even after annealing 873 K. To elucidate this mechanism, binding clusters calculated based on first...
As the plasma facing material in nuclear fusion reactor, tungsten has to bear irradiation impact of high energy particles. The surface quality may affect its resistance, and even service life reactor. In this paper, samples with different were polished by mechanical processing, subsequently conducted D2+ implantation thermal desorption. was performed at room temperature (RT) dose 1 × 1021 D2+/m2 5 keV ions, desorption spectroscopy measurements done from RT 900 K. addition, He also 50 eV He+...
In this article, Y2O3-reinforced tungsten composites are fabricated by using an improved wet chemical method combined with the spark plasma sintering (SPS). Triethanolamine (TEA) surfactant addition and appropriate calcination process innovatively introduced into method. The results show that ultrafine composite powders nano-sized Y2O3 dispersions in matrix can be obtained through Using SPS, average sizes of particles within grains at grain boundaries identified to 13.5 50 nm, respectively....
Divertor components with excellent comprehensive performance are a new research focus for nuclear fusion reactors. However, the excessive mismatch in coefficient of thermal expansion (CTE) between W and Cu poses challenge their application divertor. This paper provides review recent progress bonding technologies W/Cu monoblocks, where monoblock refers to any assembly direct interface. The monoblocks interface materials (brazing diffusion bonding) structures (surface nanosizing W, coating,...
The formation of Cu precipitates was investigated in two $\mathrm{Fe}\text{\ensuremath{-}}\mathrm{Cu}$ binary model alloys irradiated at $573\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ with fission neutrons doses from $4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ to $6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$ displacement per atom (dpa). Experimental positron annihilation results indicated that were formed even after irradiation...
To address the challenges in joining of immiscible W/Cu dissimilar metals, this study employs surface grinding treatment to induce plastic deformation and coarsening on W surface, thereby obtaining reliable joints through spark plasma sintering (SPS). The effects bonding temperature interfacial microstructure, mechanical properties thermal conductivity were systematically investigated. results demonstrate that micro-nano structure is successfully introduced into interface via combined with...
