Abstract High‐flow intensity over a well‐developed static armour layer will significantly reduce the stability of riverbed. However, at which would completely break is not known. In this study, laboratory flume experiments were conducted to analyze response high‐flow intensity. The was developed under condition steady flow with no supply sediments. increased by increasing discharge, and bed‐load rate determined evaluate whether broke. observations indicate that when bed shear stress low...
The formation and reestablishment of bed structural properties in the static armor layer is an important research subject. To address this issue, we conducted a series experiments laboratory flume that focused on reestablishment. Through automatic measurement system, obtained real-time load transport rate. surface elevation at different flow intensities was using PTS (Photo Terrain Scanning) system. results show rate increased from zero to its peak before decaying. structure response found...
AbstractBy means of heat treatment, creep properties measurement and microstructure observation, we investigated the influence treatment on TiAl–Nb alloy. Results showed that as-cast alloy consists γ/α phases with a lamellar structure. Boundaries irregular jagged shapes are located between different oriented phases. After solution aging uniform regular in were obtained, boundaries groups orientations displayed straight features. The lifetime as cast at 200 MPa/800°C was measured to be 147 h,...
The size distribution of armor layer in mountain rivers is an important factor that affects the stability river bed. However, there are relatively few studies on prediction reconstruction process after previous static becomes unstable. In response to above challenges, this study considers incipient probability sediment particles as starting point, and comprehensively coupling relationship between initial bed materials, structure, ratio, flow intensity, using a simple calculation model for...
The insulation system of one 330kV Inverted-type Oil-immersed Current Transformer (IOCT) has broken down recently. In order to find the cause accident, dielectric parameters IOCT materials with different moisture content were tested at temperature. Then, electric field distribution was calculated using data measured. strongest strength main analyzed, and extreme operating environment obtained.
Cold spray process has been demonstrated to be an attractive additive manufacturing technology develop freeform and coatings out of temperature-sensitive materials by high-velocity particle impact. However, because lower bonding strength inhomogeneous residual stress field distribution, the fatigue performance cold sprayed deposition couldn’t satisfy requirement in many engineering condition. In present work, we proposed a novel promising approach recover repairing components two laser beams...
In this work, chromium (Cr) microalloying is utilized in a model 45 steel to optimize the strength-ductility synergy. This goal realized by microstructural design strategy of introducing heterogeneous structures with nanoprecipitation and solutes at surface via Cr coating laser remelting. As result, surprisingly increased strength (i.e. ~110MPa yield strength) comparable ductility are achieved studied steel, compared Cr-free substrate. addition, self-current corrosion current also reduced an...

Reservoir operation optimization is a technical measure for flood control and beneficial owing to its reasonable reliable application of existing water conservancy hydropower hubs, while ensuring dam safety control, as well the normal power supply supply. Considering functions reservoirs, namely ecological protection, this paper firstly established two-objective optimal model reservoir group in middle reaches Yellow River. We aim maximize average output cascade minimize change flow during...
