The absorption of laser energy by pure copper powders has a huge impact on the formation high quality parts selective melting. In this paper, surface modification technology was used to treat powder improve effect powder. It found that modifying generate layer CuO film effectively improved Uniform and dense films melting parts, which solved problem preparing for high-density parts. microstructure consisted fine columnar cellular crystals. presence subcrystals dislocations in localized areas....
The graphene nano-platelets (GNPs) reinforced AZ31 alloy composites were fabricated by friction stir processing (FSP) with three multi-pass and high rotation speed. AZ31/2.14 vol% GNPs AZ31/6.43 designed. fine microstructure uniform dispersion of observed in the AZ31/GNPs composites. hardness tensile properties enhanced after cumulative FSP passes. This was attributed to grain refinement strengthening effects GNPs. corrosion resistance improved due refinement, distribution β-Al12Mg17 phase...
This paper describes the droplet transfer behavior and weld formation of laser-arc hybrid welding with cable-type wire (CWW). The was photographed in real time by using a high-speed camera. effects energy parameters on arc morphology, were studied through experimental theoretical analyses. results show that is deflected toward laser direction, deflection degree increases increasing power. interaction between enhanced rotating arc. enhances plasma, more compressed volume smaller as current...
Introduction The interaction between the materials themselves and cancer cells are rarely explored. Therefore, biological roles of raw single wall carbon nanohorn (SWCNH) on endoplasmic reticulum (ER) stress in apoptosis CNE2 were Methods ERS was induced by SWCNH, 4-phenylbutyrate (4-PBA) selected as a inhibitor ERS. co-cultured with 4-PBA SWCNH+4-PBA, respectively. Furthermore, apoptotic status its ROS (Reactive oxygen species) levels determined. Moreover, protein expression caspase 3...
Abstract In this study, magnetic field–assisted high rotational-speed stir friction welding (MFA-HRFSW) and (HRFSW) were carried out on a 1-mm-thick 6061-T6 aluminium alloy plate, the macroscopic morphology, microstructure, corrosion for, mechanical properties equipment tolerance of two types welded joints studied compared. By establishing mathematical model MFA-HRFSW process, temperature field characteristics process analysed, revealing that application rotating during (FSW) influences...
In this study, in order to achieve a better understanding of the strengthening mechanism commercially pure (CP) Ti welds, autogenously laser beam and laser-MIG hybrid welding 4.2 mm thick CP-Ti plates were performed correlation between microstructure, texture distribution mechanical properties systematically investigated. Microstructural coarsening increase microhardness observed HAZ WZ. The tensile test results suggested base metal was weak point joint for both conditions. EBSD observations...
Abstract With increasing demands of high-performance and functionality, electronics devices generate a great amount heat. Thus, efficient heat dissipation is crucially needed. Owing to its extremely good thermal conductivity, graphene an interesting candidate for this purpose. In paper, two-step temperature-annealing process fabricate ultrahigh conductive assembled films (GFs) proposed. The conductivity the obtained GFs was as high 3826 ± 47 W m −1 K . Extending time high-temperature...
The butt joint of an Al alloy ultrathin plate with a thickness 0.5 mm is realized by high rotational-speed friction-stir welding process. It overcomes the difficulty that often torn, and it cannot be formed conventional welding. results show weld surface well-formed at high-rotational speed (more than 8000 rpm), there are no obvious defects in each area section. nugget zone (NZ) recovery recrystallization structure dominated large-angle grain boundaries, size about 4.9 μm. During growth,...
Neural networks require a lot of training to understand the model plant or process. Issues such as learning speed, stability, and weight convergence remain areas research comparison many algorithms. The application neural control interior permanent magnet synchronous motor using direct torque (DTC) is discussed. A network used emulate state selector DTC. are back-propagation radial basis function. To reduce patterns increase execution speed process, inputs switching table converted digital...
