The microstructure and tensile property of Al0.2Co1.5CrFeNi1.5Ti0.3 high entropy alloy (HEA) processed by selective laser melting (SLM) have been studied in comparisons to that fabricated traditional cast & wrought (C&W) route. C&W samples were annealed then aged at 750 ℃ for 50 h promote precipitation strengthening L12 structured phase FCC matrix. By contrast, SLM directly from the as-built condition, which possessed sub-micron dendritic segregation, internal stress nano oxides; result was...
Understanding the local chemical ordering propensity in random solid solutions, and tailoring its strength, can guide design discovery of complex, paradigm-shifting multicomponent alloys. First, we present a simple thermodynamic framework, based solely on binary enthalpies mixing, to select optimal alloying elements control nature extent high-entropy alloys (HEAs). Next, couple high-resolution electron microscopy, atom probe tomography, hybrid Monte-Carlo, special quasirandom structures,...
This article presents a collection of data on approximately 150 copper-based alloys. The compilation is based articles published since 1993 and consists about 1830 records. Each record contains unique set descriptors, such as composition processing route, targets, including properties hardness, yield strength, ultimate tensile electrical conductivity. dataset includes information the in mass percent 20 alloying elements, hundreds temperature-time thermal treatments thermomechanical...
A polarization-independent liquid crystal phase modulation using polymer-network crystals in a 90° twisted cell (T-PNLC) is demonstrated. T-PNLC consists of three layers. Liquid (LC) directors the two layers near glass substrates are orthogonal to each other and those modulate eigen-polarizations an incident light. As result, light experience same shift. In middle layer, LC perpendicular substrate contribute no The shift electrically tunable polarization-independent. does not require any...
Cesium (Cs) incorporation and sulfurization on copper indium gallium selenide solar cells are the keys to improving device quality. In this study, we explore impact of Cs modulation sulfur-containing Cu(In, Ga)(S, Se)2 (CIGSSe) absorbers, resulting in a performance increase over 2%, reaching 18.11%. The improvement stems from widened surface bandgap, grain boundary (GB) passivation, moderate injection blocking layer. bandgap widens 1.44 2.63 eV after incorporation, confirmed by ultraviolet...
Swine wastewater pretreated by solid–liquid separation was optimized for biogas production and water purification. Dynamic diversity of the bacterial community in anaerobic plug flow reactor investigated under various temperatures hydraulic retention times (HRT). Results batch experiments indicated that optimal operating conditions, production, methane rate, chemical oxygen demand (COD) removal efficiencies increased up to 26%, 52%, 44%, respectively. In continuous experiments, conditions...
The oxidation of six NbTi-i refractory medium- and high-entropy alloys (NbTi + Ta, NbTi CrTa, AlTa, AlMo, AlMoTa AlCrMo) were investigated at 1000 °C for 20 h. According to our observation, increased Cr content promoted the formation protective CrNbO4 Cr2O3 oxides in CrTa AlCrMo, enhancing resistance. addition Al resulted AlTi-rich oxide AlTa. Ta complex (MoTiTa8O25 TiTaO4) decreased Meanwhile, Mo's low oxygen solubility could be beneficial resistance while Cr2O3/CrNbO4 layers formed. In...

This research focused on oxidation behaviours of Al-bearing Cr-based alloys at 1100-1400 ˚C for up to 24 hours. Experimental observations indicate that Al2O3 protective oxide formed mainly the matrix BCC phase, and complex oxides formation occurred in vicinity C14 Laves such as Cr2O3, AlTaO4, CrTaO4, Ta2O5, leading some internal AlN formation. Although increase Al content could promote Al2O3, it also caused spallation due CTE mismatch. study may provide insights development future...
A polarization-independent liquid crystal (LC) phase modulation using polymer-network crystals with orthogonal alignments layers (T-PNLC) is demonstrated. T-PNLC consists of three layers. LC directors in the two near glass substrates are to each other. In middle layer, perpendicular substrate. The advantages such include polarizer-free, larger shift (~0.4π rad) than residual type (<0.05π rad), and low operating voltage (< 30V<sub>rms</sub>). It does not require bias for avoiding...
Coupled-cavities are employed in the traveling-wave amplification of microwaves as slow wave structures. The general behavior coupled-cavity structures can be suitably described by using a lumped circuit model.
