Based on the artificial pollution tests, flashover performance of various types DC porcelain and glass suspension insulators as well composite long-rod were analyzed compared. The test results show that there is a nearly linear relation between voltage disc-type insulator string length. gradients are affected by their materials shed shapes. antipollution performances superior to those with same profile. higher than or ones. exponent characterizing influence salt deposit density dependent...
Under part-load conditions, a Francis turbine often suffers from very severe low-frequency and large-amplitude pressure fluctuation, which is caused by the unsteady motion of vortices (known as “vortex ropes”) in draft tube. This paper first reports our numerical investigation relevant complex flow phenomena entire tube, based on Reynolds-averaged Navier–Stokes (RANS) equations. We then focus physical mechanisms underlying these somewhat chaotic draft-tube under condition. The stability...
Hardness, as a typical mechanical property of dispersion-strengthened tungsten alloy, is influenced by various coupled factors. This paper aims to identify the key factors affecting hardness alloys with different carbides and oxides reinforcement phase in order enable high-throughput prediction hardness. A dataset was established alloy target variable, features included content phase, Vickers melting point valence electron number sintering temperature, time, pressure, relative density, grain...
The influence of Eu additions upon the silicon phase and mechanical properties Al-40Zn-6Si alloys have been investigated via scanning electron microscopy (SEM) high-angle annular dark-field transmission (HAADF-STEM). primary Si was discovered to be remarkably refined modified nodular with 0.5% addition. Meanwhile, plate-like eutectic a fibrous structure. effect on clarified from five aspects: (a) adsorption single atomic column at twin boundary, inducing stacking faults parallel twins, (b)...
With the miniaturization of solder joints and deterioration serving environment, much effort had been taken to improve properties Sn-based lead-free solders. And fabrication composite alloys by addition nanoparticles is one effective ways enhance properties. In this paper, recent research progress on reviewed summarizing relevant results in representative ones Sn-Ag-Cu (SAC), Sn-Bi, other multielement alloys. Specifically speaking, effect added evolution wettability, microstructure...
In this study, scanning electron microscopy (SEM), backscatter diffraction analysis (EBSD), and probe microanalysis (EPMA) were used to investigate the impact of rare-earth Sc on interface microstructure mechanical properties Al/steel bimetallic composites fabricated by liquid–solid casting. With addition 0.3% Sc, morphology eutectic Si changed from needle-like fibrous granular. The did not change types intermetallic compounds in reaction layer, which comprised Al5Fe2, τ1-Al2Fe3Si3, Al13Fe4,...
The effects of carbon contents on wear resistance were investigated for Cr-Si-Mn low alloy cast steels. abrasive impact behavior was also analyzed. results showed that, with the increase content in steels, metallographic structure partly transformed from lath martensite to acicular gradually, hardness increased and toughness decreased distinctly, furthermore, resistant first then decreased, that mainly caused by mechanism changed form plastic fatigue brittle fracture wear.
