Rejuvenation heat treatments can restore the microstructures and mechanical properties of the degraded turbine blades in gas turbine engines.Herein we analyze the effects of rejuvenation heat treatments on the microstructural characteristics and mechanica
Cerium dioxide has a comparatively lower Ce4+/Ce3+redox pair,which leaves abundant oxygen vacancies on oxide lattice,also making incorporation of foreign ion and subsequent applications feasible and convenient.In this work,a series of cerium-yttrium mixed
Hot-rolled high-Mg-alloyed Al-Mg alloy(Al-9.2 Mg-0.8 Mn-0.2 Zr-0.15 Ti,labeled as 5 A12)plates were successfully friction stir welded at rotating rates ranging from 750 to 1500 r·min-1 at a constant welding speed of50 mm·min-1.The jo

The as-cast Cu-doped Fe83Ga17 alloys were prepared by arc-melting.The microstructures and magne-tostrictions of(Fe83Ga17)100-xCux(x=0,3,6,9,12,15)alloys were in
文中提出了一种基于泡克耳斯效应的集成光学电压传感器测量直流电压的研究方案,光纤光路结构采用熊猫型保偏光纤与低偏光纤相结合以提高系统光路的互易性,理论上利用琼斯矩阵推导了入射光光路数学传输模型,得出干涉光强与干涉信号的关系表达式。针对该光学电压传感器设计方案,搭建了实验平台并对系统进行了0～15 V直流实验,实验结果表明该传感器输入电压与数字输出曲线之间具有良好的线性关系,最大非线性误差为0.2%,
Weight reduction plays an important role in reducing fuel and emissions,and the heat-treatable 6016 aluminum alloy exhibits excellent application prospect in automobile lightweight.In this paper,ingot with constant Mg/Si ratio and decreased Mg and Si cont
The metal-organic-decomposed lanthanum cerium oxide(LaCeO2)solution was spin-coated on p-type Si substrate to form thin films.The method of microwave-assisted annealing was adopted to modify the surface properties of the deposited thin films.Th
为了有效监测局部放电信号,利用FPGA的高速并行处理能力,设计一种基于FPGA的特高频局部放电监测硬件实现系统。文中介绍了系统的硬件设计及FPGA实现原理。系统使用提升小波变换对采集数据进行脉冲提取,然后对有效脉冲进行特征提取,最后将提取的特征参数送入PC端,使用DBSCAN将脉冲的特征提取结果进行聚类分离。实验结果表明,基于高速FPGA设计的局部放电监测硬件系统能将不同脉冲信号有效分离。
A novel phenomenon of spontaneous positive exchange bias(PEB)is reported in SrFeO3-x/SrCoO3-x epitaxial bilayer without undergoing any magnetic field treatment.When inserting a thick SrTiO3(STO)nonmagnetic spacer(about 6 nm)into the bilayer interface,this
