Spin transfer nano-oscillators (STNOs) are nanoscale devices which promising candidates for on-chip microwave signal sources. For application purposes, they expected to be nano-sized, have broad working frequency, narrow spectral linewidth, high output power and low consumption. In this paper, we demonstrate by micromagnetic simulation that magnetic skyrmions, topologically stable magnetization configurations, can excited into oscillation a spin-polarized current. Thus, propose new kind of...
Wire and arc-based additive manufacturing (WAAM) is a rapidly developing technology which employs welding arc to melt metal wire for purposes. During WAAM of thin-walled structures, as the wall height increases, heat dissipation substrate slowed down gradually so solidification molten pool, leading variation bead geometry. Though reducing input via adjusting process parameters can alleviate this issue, suggested by previous studies, it relies on experience large extent inevitably sacrifices...
Al–Zn–Mg–Cu alloys are widely used in large-scale structural components of the aerospace industry, but research on wire and arc additive manufacturing (WAAM) is lacking. This focused grain refining by adding TiN particles during WAAM. The WAAM component was filled with equiaxed grains orientation became more random because coarse columnar were eliminated. average size reduced from a value 459 μm to 104 μm. Heterogeneous nucleation main mechanism, located along boundaries also helped prevent...
In this study, Al-Zn-Mg-Cu alloy components were prepared using wire arc additive manufacturing (WAAM). Through multi-scale characterisation technology, performance testing and slow strain rate tensile (SSRT) testing, the microstructure, mechanical properties stress corrosion cracking (SCC) susceptibility of WAAM studied, revealing generation mechanism inhomogeneity anisotropy. The results show that with increase thermal cycles, matrix precipitates (MPs), grain boundary (GBPs)...
This paper proposes a hybrid WAAM (wire arc additive manufacturing) and milling process (HWMP), highlights its application in the fabrication of stiffened panels that have wide applications aviation, aerospace, automotive industries, etc. due to their light weight strong load-bearing capability. In contrast existing joining or machining methods, HWMP only deposits stiffeners layer-by-layer onto an thin plate, followed by minor irregular surfaces, which provides possibility significantly...
