Lead selenide (PbSe) colloidal quantum dots (CQDs) are promising candidates for optoelectronic applications. To date, PbSe CQDs capped by halide ligands exhibit improved stability and solar cells using these as active layers have reported a remarkable power conversion efficiency (PCE) up to 10%. However, more prone oxidation, requiring delicate control over their processability compromising Herein, an efficient strategy that addresses this issue in situ cation-exchange process is reported....
Deformation of an as-rolled rare earth Mg-2Y-0.6Nd-0.6Zr alloy, at different temperatures, was carried out along the BC (90° anticlockwise rotation samples after each ECAP pass) route by equal channel angular pressing (ECAP). The effects deformation temperature and predeformation on microstructure magnesium alloy were determined examination. slip systems texture change investigated X-ray diffraction (XRD) electron backscattered (EBSD), deformation. results showed that seven passes rolling,...
Chemical vapor deposition (CVD) is a promising technique for the preparation of Wbased plasma-facing materials (PFMs).An overview microstructure, chemical composition, thermal conductivity, stability, shock performance under disruption-like and edge localized mode (ELM)-like transient heat load, neutron irradiation CVD-W has been given in our previous work.However, fusion applications, additional properties need to be assessed.To this end, deuterium (D) permeability, D plasma performance,...
A fine-grained Mg-2Y-0.6Nd-0.6Zr alloy was processed by bar-rolling and equal-channel angular pressing (ECAP). The effect of ECAP on the microstructure mechanical properties rolled investigated optical microscopy, scanning electron backscattered diffraction a room temperature tensile test. results show that obtained high strength poor plasticity after rolling. As number passes increased, grain size gradually reduced texture basal plane weakened. ultimate first increased then decreased, yield...
W–Y2O3 alloy with low DBTT (ductile-brittle transition temperature) and high RCT (recrystallization temperature), processed by energy rate forging (HERF) was exposed to ITER-like steady-state transient hydrogen plasma in the linear generator Magnum-PSI. The heat fluxes were range of 8.35–16.32 MW . m−2, resulting surface base temperatures samples 1271 °C 1982 °C. applied peak flux a frequency 5 Hz (a total 1000 pulses) about 0.50 GW m−2. exposure time ~220 s. No obvious morphological change...
The microstructure evolution, texture, mechanical behavior and twin deformation of the ECAPed Mg-2Y-0.6Nd-0.6Zr alloy at room liquid nitrogen temperature were investigated by rolling samples. ECAP processed material appeared texture 45° to extrusion direction its yield strength reached 93.6 MPa. results showed that cryorolling encourages twinning in alloy, enhancing tensile texture. Activation {10-12} during was found be more pronounced cryorolled samples than cold rolled owing a lower...
Mg–2Y–0.6Nd–0.6Zr alloy was first deformed by equal channel angular pressing (ECAP), then rolled and under ultralow temperature conditions (liquid nitrogen immersion), finally annealed. Optical microscopy (OM), electron backscatter diffraction technology (EBSD), transmission (TEM) were used to analyze the evolution of multiscale microstructure changes in mechanical properties temperatures various annealing conditions. The results showed that treated with ECAP obtained fine grains, a large...
The application of martensitic transformation to improve mechanical properties demonstrates one the most significant methods in study alloys. recently developed non-equiatomic high entropy alloy (HEA) activates induced plasticity (TRIP) effect via tailoring Mn content performance. However, mechanism phase stabilization is rarely reported. In this work, effects on stability and Fe40Mn40-xCo20Crx (x=5,10,15,20) alloys were investigated using first-principle calculations. A new microscopic...
