This paper obtained an additively manufactured high-strength Al-Li alloy by laser powder bed fusion (LPBF) based on a third generation AA2195 raw material. The relationship between the process optimization, microstructure evolution, and mechanical properties of as-printed (AP) heat-treated (HT) specimens was established for first time to explain intergranular fracture sensibility during LPBF reveal dominant precipitation strengthening mechanism induced subsequent heat treatment. order AP at...
Molten salt energy storage technology shows great potential in a sustainable integrated system for its excellent thermal efficiency and environmental adaptability, it has received much attention from the academic community. To improve of traditional dual-tank heat systems, new distributed single tank with an internal source was proposed. The designed according to API 650 EN 13445-3:2012 specifications, specific data obtained by combining application examples. results show following: (1)...
In this paper we propose a gold-plated photonic crystal fiber (PCF) refractive index sensor based on surface plasmon resonance (SPR), in which gold is coated the external of PCF for easy fabrication and practical detection. The finite element method (FEM) used performance analysis, numerical results show that thickness film, analyte, radius air hole first layer, second central can affect sensing properties sensor. By optimizing structure, maximum wavelength sensitivity reach 11000 nm/RIU...
A surface plasmon resonance (SPR) temperature sensor based on a photonic crystal fiber (PCF) filled with silver nanowires is proposed in this paper. We inject ethanol solution into the grapefruit PCF to realize sensing. The sensitivity of can reach -433pm/∘C by numerical simulation, and experimental result -160pm/∘C. Simulations experiments show that wavelength peak will blueshift invalidity nanowires, effect weaken. It provide reference for realization application other SPR sensors PCF.
Ultra-high-frequency (UHF) partial discharge (PD) online monitoring is an effective way to inspect potential faults and insulation defects in power transformers. The construction of UHF PD system a challenge because the high-frequency wide-frequency band signal. This paper presents novel, intelligent sensor for based on new method, namely level scanning method. can directly acquire statistical characteristic quantities characterized by low cost, few data output transmit, Ethernet...
The purpose of enhanced heat exchange technology is to improve the performance equipment, but increase resistance causes decrease energy consumption and economic benefits. Then comprehensive evaluation index used evaluate equipment. In process numerical simulation, there no unified standard for value catchment scale. this paper, by changing length entrance exit external passage tube-fin exchanger, change law transfer (j⋅f−1/3) exchanger at different Reynolds numbers was studied simulation....

Microalloying vanadium can change the segregation state of Nb element in IN718 alloy, reduce formation harmful Laves phase and refine dendritic structure alloy during laser process. Therefore, alloys with V content from 0.081 to 1.88 wt.% were prepared evaluated. Metallographic microscopy scanning electron used observe corresponding morphology, structure, distribution elements. First all, it was found that addition refines grain size reduces primary dendrite arm spacing. Secondly, adding...
The health of the landing gear retraction/extension(R/E) hydraulic system may be assessed using fuzzy comprehensive evaluation (FCE), however traditional FCE method depends solely on human assessment by specialists, which is excessively subjective. To address issue excessive subjective variables in assessment, an improved model based enhanced risk coefficient provided, includes four consideration indexes: failure probability, severity, detection difficulty, and repair difficulty. reduce...
