In order to achieve high-quality welding of aluminum alloys, reasonable control heat input is critical. Different combinations parameters can the same input, however, relevant research results has not been reported. this paper, pulsed-gas metal arc (P-GMAW) 4047 Al–Si alloy was used as object. Combining design current, voltage and speed, three sets with were obtained, experiments carried out on them. The formation, microstructure mechanical properties weld bead analyzed. show that under...
Abstract Asynchronous quantum key distribution protocol (AMDI‐QKD) is a high performance while it can outperform the Pirandola–Laurenza–Ottaviani–Banchi (PLOB) bound without need of phase‐locking and phase‐tracking techniques. However, applies relative phase information communicating parties for encoding, drift reference frame inevitably affects QKD system, whereas independent (RFI‐QKD) has advantage tolerating slow change frame. In this study, frame‐independent asynchronous (RFI‐AMDI‐QKD)...
This study aims to improve the prediction accuracy of diffusion trajectory radioactive pollutants in atmosphere. First, based on traditional Gaussian plume model, model is improved by introducing two key control factors: rainfall intensity and ground roughness. Secondly, factors affecting gas under different intensities roughness are analyzed, as well characteristics atmosphere influence these factors. Finally, taking nuclide leakage Daya Bay Nuclear Power Station an example, according...
Various piezoelectric beam based approaches have been well studied to support vibrational energy harvesting, where the natural frequency of harvester is purposely designed match external vibrations. Note that vibrations usually exhibit a low nature, which significantly limits output conversion because operational for such systems much higher. In this work, we propose novel compliant mechanism combining structure with multi-stable mechanism, capable harvesting multiple up modes improve...
A pulsed current is introduced into the traditional coaxial laser cladding process to decrease porosity of layer.The magneto contraction force caused by exerted on molten pool squeezes gas out and compensates shrinkage during solidification.As a result layer decreased an extremely low degree.Simultaneously, grain finer with added supercooling degree current.The microhardness equiaxed zone in cross section also increases.
Coarsening is a metallurgical process that related to solute transmission and system energy decrease. However, for the coarsening behavior of L12 precipitate in high-entropy alloys, influence moving boundary still an open question. Here, we found accelerates discontinuous phase. The multiple defects-accelerated diffusion continual particle-capturing ability provide high-efficiency transport fast-coarsening kinetics In addition, boundary-encountered assisted formation mechanism also validated...
