Stable magnetic droplet solitons in spin-transfer nanocontacts [PDF]

open access: yesNature Nanotechnology, 2014
Magnetic thin films with perpendicular magnetic anisotropy (PMA) have localized excitations that correspond to reversed dynamically precessing magnetic moments, known as magnetic droplet solitons. Fundamentally, these excitations are associated with an attractive interaction between elementary spin-excitations (i.e., magnons) and were predicted to ...

Relationship Between Metal Vapor in Arc and Droplet Transfer Mode in GMAW

open access: yesTaiyuan Ligong Daxue xuebao, 2022
The relationship between metal vapor in arc and droplet transfer mode in GMAW was reviewed. The results show that when welding with high current and corresponding welding parameters and different shielding gases, the conductivity of the vapor in arc ...

Droplet deformation by short laser-induced pressure pulses [PDF]

open access: yes, 2017
When a free-falling liquid droplet is hit by a laser it experiences a strong ablation driven pressure pulse. Here we study the resulting droplet deformation in the regime where the ablation pressure duration is short, i.e. comparable to the time scale on

Effect of energy parameters on droplet transfer behavior and weld formation in laser-arc hybrid welding with cable-type welding wire

open access: yesJournal of Materials Research and Technology, 2023
This paper describes the droplet transfer behavior and weld formation of laser-arc hybrid welding with cable-type welding wire (CWW). The droplet transfer behavior was photographed in real time by using a high-speed camera.

Heat transfer within combusting droplets [PDF]

open access: yesProceedings of the Combustion Institute, 2007
The improvement of the basic understanding of heat transfer in sprays is a key point in many engineering applications. In this paper, the temperature field within combusting ethanol droplets in linear stream is investigated by the two-color laser induced fluorescence technique. Additionally, a heat transfer model within the droplet is developed, taking

Effect of Process Parameters on Arc Shape, Macroscopic Features, and Microhardness in Pulsed GMA–Additive Manufacturing

open access: yesCrystals, 2023
Gas metal arc welding-based additive manufacturing (GMA–AM) is a promising, low-cost approach to fabricate large-scale and complex geometry components using layer-by-layer deposition of metals. However, the low forming accuracy of GMA–AM still limits its
