The microstructure and mechanical properties of Ti-3.5Al-5Mo-6V-3Cr-2Sn-0.5Fe high strength titanium alloy sheets prepared by unidirectional cold rolling two-step cross were investigated. Results showed that the β phase grains refined significantly followed solution treatment for a short time. Compared to rolling, time after could reduce non-uniformity sheets. After aging at 550 °C, anisotropy still existed in rolled sheets, tensile was highest along direction. treatment, process sheet not...
Silicon germanium (SiGe) alloys hold promise for thermoelectric power generation at high temperatures and have been applied in deep-space missions. However, enhancement of the dimensionless figure-of-merit (ZT) is still needed practical civil applications SiGe. In this work, we report high-performance oxide/SiGe bulk composites that were obtained via hot-press sintering mixed powders composed phosphorus (P)-doped SiGe prepared mechanical alloying, using a ball-milling technique La–Nb-doped...
Flexible thermoelectric materials are presented with potential applications in electronic devices and energy conversion due to their convenient preparation, good flexibility, various forms. However, as ductility is rarely observed inorganic semiconductors ceramic insulators, reports on of oxide flexible sparse. Here, we report a new method for the synthesis Na1.4Co2O4 material based bulk materials, which prepared by self-flux painted print paper. Seebeck coefficient power factor obtained...
The Supercritical Carbon Dioxide (SCO2) Brayton cycle has been getting more and attentions all over the world in recent years for its high efficiency compact components. compressor is one of most important components cycle. Different from traditional working fluid, SCO2 a risk condensation at impeller inlet because particular properties near critical point. In order to determine possibility condensation, concept called “Condensation Margin (CM)” suited introduced. It associated with total...
La2O3, Al, and CuO powders were used as raw materials pure copper a matrix; La2O3 was added to an Al–CuO system form new La2O3–Al–CuO reaction system. The matrix composites prepared by in situ synthesis technique the near-melting casting method. products, morphology, size, distribution of observed scanning electron microscopy, energy dispersive spectroscopy, transmission while effect on products microstructure, hardness, conductivity studied. results show that size morphology Al2O3 particles...
This paper addresses the effects of Ce-rich mischmetal on microstructure evolution a 5182 aluminum alloy during annealing and rolling processes. The was added to an as-cast in induction furnace, this followed by homogenized at 450 °C for 24 h operation. mechanical properties’ analysis Al were characterized. results show that could modify microstructure, refine α-Al grains, break network distribution Mg2Si phases, prevent Cr Si atoms from diffusing into Al6(Mn, Fe) phase alloys. elements also...
SUMMARY The filtration and retention characteristics of nicotine, phenol, benzo[a]pyrene (B[a]P), 4-(methylnitrosamino)-1- (3-pyridyl)-1-butanone (NNK), crotonaldehyde, hydrogen cyanide (HCN) ammonia in conventional cellulose acetate fiber filters were investigated. By quantitatively analyzing their contents released mainstream smoke retained filters, efficiencies, taken as the ratio filter content to total yield, determined under both International Organization for Standardization (ISO)...
Herein, SnO2- and ZnO2-doped (1.5 wt.%) composite Cu powder was prepared by mechanical alloying (MA) respectively, both the contact materials of oxide-doped alloys were subsequently obtained canned hot-pressing sintering with hot extrusion combined.
