It is shown by electron diffraction and microscopy that the first stage in crystallization of chemically electrolytically deposited amorphous Ni–P alloys on heating to 250°C an f.c.c. metastable phase α with a=0·55 nm. In second crystallization, at 270–400°C, hexagonal phases α1, α2 α3 are formed. These have same a=0·672 nm but different c parameters, latter being ratio 2:3:8 c(α1)=0·952 They originate from (001)hex parallel {111}α ⟨210⟩hex ⟨110⟩α. The growth habit α1 exhibits a...
AbstractElevated temperature compressive deformation behaviour of TA15 titanium alloy was investigated at temperatures from 1023 to 1273 K and strain rates 10−3 1 s−1. It found that the flow stresses dropped with increasing decreasing rate. The microstructure observed analysed using optical microscope. volume fraction shape primary alpha phase are influenced by rate.Keywords: TITANIUM ALLOYDEFORMATIONFLOW STRESSMICROSTRUCTURE
Heterointerface engineering is a promising approach to promote electrocatalytic oxygen evolution reaction (OER) performance. This allows the interfacial electronic structure be modified, which induces redistribution of charges. However, preparing and designing electrocatalysts with appropriate band structures outstanding performance remains challenge. Herein, CoP/CeO2 p-n heterojunction hollow nanostructure (h-CoP/CeO2) was constructed by electrospinning selective phosphorization process....
AbstractAbstractAn evaluation model is proposed for the strain and rate of a localised deformation band produced by an orthogonal cutting test upon high strength low alloy steel tempered at 600°C after quenching. It can be used to determine first deformed zone (FDZ) in chip also second (SDZ) bottom chip. These zones were severely rates up 4·6 ×104−4·2 ×106s−1, with strains as 1190–2760%. X-ray diffraction showed that SDZ consisted ferrite retained austenite which was not detected matrix....
Abstract Two types of light emission characteristics at the off‐state breakdown GaN HEMTs were observed and investigated. One them showed a yellow band electroluminescence characteristic room temperature, which might be attributed to same origin luminescence (YL) defects. The electric field dependence this YL‐like was found more sensitive than other type. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
In this paper, the spherical Fe-C micro-electrolysis materials (Fe-C MEM) were prepared using iron powder, activated carbon corn straw, and bentonite as raw materials. The preparation conditions optimized by single factor test showed MEM had a high crystal violet removal strength under 1:1 of Fe/C ratio, 2% straw content, 25% 900 °C sintering temperature. porous specific surface area 108.069 m2/g with an even distribution zero-valent carbon. maximum capacity CV was 105.48 mg/g at 25 °C....
Low-cost polymeric channel waveguides and Y-junction geometries without residual layer have been fabricated. They good profiles propagation performances. The waveguide's loss is 0.97 dB/cm including the material loss. y-junction's insertion 1.38 dB.
