Closed-Loop Control of Droplet Transfer in Electron-Beam Freeform Fabrication [PDF]

open access: yesSensors, 2020
In the process of electron-beam freeform fabrication deposition, the surface of the deposit layer becomes rough because of the instability of the feeding wire and the changing of the thermal diffusion condition.

Contactless mass transfer for intra-droplet extraction [PDF]

open access: yesScientific Reports, 2020
AbstractThis study demonstrates the possibility of “contactless” mass transfer between two aqueous slugs (droplets) separated by an oil slug in Taylor flow inside milli-channels. Separation of the alternating aqueous slugs at the outlet was performed by switching a couple of solenoid valves at branched outlets according to signals obtained by an ...

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 ...

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

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 ...

Global Droplet Heat Transfer in Oxygen Steelmaking Process

open access: yesMetals, 2022
Generated droplets in a basic oxygen furnace (BOF) process create an interfacial area between metal and slag/emulsion that helps in heat transfer during different stages of the blowing period.
