Abstract null null As a new refining technology, the electron beam smelting has been widely used for alloy purification due to its advantages in removing volatile impurities and non-metallic inclusions. However, the evaporation of alloy elements during the smelting process leads to uncontrollable alloy composition. In order to predict the volatilization behavior of the alloy elements, various theoretical models have been proposed. These models can be well applied to binary or ternary alloys, but...

Abstract null null To uncover the mechanical performance and micro-structure of Al/L12-Al3Zr interface through density functional theory, four interface models are investigated considering two different terminations of L12-Al3Zr surfaces along the [001] direction. Results indicated stacking sequence and atom type between two phases influences the mechanical performance of the interface quite well. The interface consisting of four Al atom-terminated Al(001) slab as well as one Al and four Zr atom...

Abstract null null AlCrFeCoNiV high entropy alloy (HEA) was used as a binder for the densification of WC-W2C eutectic particles by spark plasma sintering (SPS) at different sintering temperatures (1000–1400 °C). The relationship between phase composition and microstructure of (WC–W2C) – 10 wt% AlCrFeCoNiV metal-matrix composites depending on the sintering temperature was investigated and mechanical properties were determined. The bcc solid solution of HEA binder formed during mixing with WC-W2C ...

Abstract null null We realized the control on the crystal structure of GaAs nanowires (NWs) by silicon (Si) doping and V/III ratio. This viewpoint has been clearly evidenced by Raman spectrum combined with high-resolution transmission electron microscopy (HRTEM). Undoped GaAs NWs generally show a mixture of zinc blende (ZB) and wurtzite (WZ) phases; the addition of Si dopant and high V/III ratio are beneficial for the nucleation of ZB structure. Field effect transistor (FET) devices were fabrica...

Abstract null null Fe3O4 nanoparticles as a magnetic adsorbent were prepared and used to effectively remove tetracycline (TC) from neutral aqueous solution. Several characterizations show that the as-prepared Fe3O4 nanoparticles possess a saturation magnetization of 79.4 emu/g, a specific surface area of 58.8 m2/g and an average particle size of 25 nm. Batch experiments were carried out to investigate the adsorption behavior and mechanisms. For a 100 ml TC solution with an initial concentration ...
Abstract null null To examine the relationship between the X-ray Diffraction (XRD) pattern and microstructure of the surface of E690 high-strength steel induced by laser shocks, X-ray diffractometry and transmission electron microscopy (TEM) were used to detect the laser-impact zone on the steel surface to obtain its diffraction pattern and microstructural morphology, followed by the establishment of a surface microstructure response model of the E690 high-strength steel under laser shock. The g...

Abstract null null The experiments and molecular dynamics simulations were employed to further understand the morphology evolution and failure mechanism of the TA15/Ti2AlNb interface. The results show that the asymmetric diffusions, caused by the difference of the diffusion coefficient and crystal structure, have played a significant role in the microstructure and mechanical properties. The diffusivity of Ti elements from TA15 was much better than those Nb and Al from Ti2AlNb base alloy owing to...

Abstract null null To investigate the growth characteristics and corrosion resistance of Micro-arc oxidation (MAO) coatings prepared from Al–Mg composite plates under sodium silicate electrolyte, comparative experiments were performed using single plate Al and Mg. The results showed that the breakdown of the Mg plate (P–Mg) in the Al–Mg composite plate occurred first than the Al plate (P–Al). The coating thickness of P–Al and P–Mg gradually converged with time. Because after the Al and Mg plates...
Abstract null null The ozone synthesis and decomposition processes in a heated ozone generator (10–70 °C) in a pulse discharge was investigated. Concentrated ozone (up to 200 g/Nm−3) was also decomposed at temperatures of 10–90 °C without discharges for comparison. It was found that for residence times up to approx. 4 s, the gas temperature in the gap has no significant effect on the ozone concentration drop. However, the appearance of electrical discharges in the gap causes that even at low tem...
Abstract null null An investigation on the corrosion protection and electrical conductivity films on metal bipolar plates can be achieved through magnetron sputtering. This work characterized the microstructures of TiN–Ag nanocomposite deposited at different temperatures with thermal stabilization. All the TiN–Ag films show adequate electrical conductivity with the interfacial contact resistance (ICR) of 4.81, 4.78, 4.52, 4.18 mΩ cm2 at the deposition temperature of 200 °C–350 °C on SS substrate...
