This letter presents an ultrawideband miniaturized ultrathin flexible metamaterial absorber (MMA) based on frequency selective surface (FSS). The proposed MMA consists of inner planar helix and four groups outer convoluted lightweight indium tin oxide resistive film etched a transparent substrate polyethylene terephthalate substrate. demonstrates stable absorption across the range 1.98 to 25.88 GHz, achieving remarkable maximum fractional bandwidth 171.6%. unit cell size is 0.06...
Abstract For lead‐cooled fast reactors and accelerator‐driven subcritical systems, the surface corrosion behavior of candidate structural materials in lead–bismuth eutectic (LBE) is a key issue, which determines whether material applicable. The two typical MAX phases, Ti 3 SiC 2 AlC , were immersed static LBE with saturated oxygen concentration at 500°C for up to 3000 h. behaviors analyzed by scanning electron microscope, energy‐dispersive X‐ray, X‐ray diffraction, Raman spectra....
In this paper, the effects of Bi2O3 doping on mechanical properties PbO ceramic pellets were studied. Different ratios Bi2O3/PbO (i.e., xBi2O3-(1-x) PbO, where x is 0, 1, 3, 5, or 7 wt.%) fabricated and sintered at 570, 620, 670 °C. Mechanical including density, hardness, flexural strength, sintering studied for each aforementioned compositions. Phase composition, microstructure, worn surfaces composites characterized by scanning electron microscopy X-ray diffraction (XRD). The XRD analysis...
Mechanical properties of the electron beam weld zone, which are different from base metal, Hastelloy C-276 were studied by small punch test (SPT) technology. Load–displacement curves and material obtained using miniaturized plate-type specimens (3mm diameter×(0.15-0.4) mm thick) metal respectively. The result shows that maximum load is larger than under same thickness, meaning higher strength weld. Furthermore, finite element method analysis was performed to investigate effects specimen...
The structure material corrosion in liquid lead or lead-bismuth eutectic (LBE) is a tremendous limitation of the development cooled fast reactors and accelerator driven sub-critical system (ADS). Keeping certain oxygen concentration can prevent steel pipe from by LBE. Through dissolution precipitation PbO ceramic has been found to control successfully. This paper presents research on new technology processing oxide ceramic. raw material, pure powder deionized water, without any other...
The application of organic solid–liquid phase change materials (PCMs) is limited for the leakage problem after and high rigidity. In this work, a novel flexible solid–solid PCM (DXPCM) was synthesized using block copolymerization process with polyethylene glycol (PEG) as energy storage segment. transition temperature (from 36.2 to 49.4 °C) enthalpy 83.27 123.35 J/g) DXPCM could be changed through adjusting molecular weight PEG. introduction hard chain segments endowed excellent flexibility,...
Abstract Alumina-forming Austenitic (AFA) steel is one of the candidate corrosion-resistant structural materials for lead-cooled fast reactors, exhibiting excellent high-temperature corrosion resistance. However, its mechanisms in lead-bismuth eutectic (LBE) environment at design operating temperature reactors have not been fully elucidated. In this study, AFA was immersed static LBE with saturated oxygen 500 °C 3000 hours. The behavior samples obtained by analyzing morphology cross section...
Due to its good creep strength, molybdenum (Mo) single crystal is used for space thermionic reactor fuel element. However, stray grain formation during Mo welding leads the degradation of mechanical properties. In this paper, welded by electron beam and joint properties are evaluated means small punch test (SPT). The load-displacement curves matrix fusion area measured. experimental data fit establish relationship between yield load standard strength. results show that strength much lower...
Processing of nuclear waste has become an important issue nowadays. A microwave disposal method for solid mainly containing Ni, Fe element and their oxide produced in the primary loop is investigated this article. The powder waste, which treated as absorber energy source curing, was doped curing agent that using SiO2 a main component. In experiment, household oven (Microwave-frequency: 2.45GHz, Output power: 700W), thermal effects non-thermal make samples heated to high temperature quickly...
An experimental setup was designed to find out behavior of deposition thickness corrosion products. This is on the bases ITER (International Thermonuclear Experimental Reactor) loop. The experiment done for different values pH study its effect thickness. System pressure kept at 0.5 MPa with maximum limit temperature 150°C. value in range 7.00–10.50. Artificial particles (Fe3O4) were introduced manually loop, which allowed stabilize. Four test tubes used determine deposition, and these points...
