Slag Evaluation to Reduce Energy Consumption and EAF Electrical Instability [PDF]
Materials Research, 2016 In steel mills that operate with electric arc furnaces (EAF), it is interesting to ensure greater stability to the electric arc to aim at less distortion in the electrical system, with consequent reduction in electric power consumption.

Cosmic radio noise absorption events associated with equatorward drifting arcs during a substorm growth phase [PDF]
, 2004 International audienceCosmic radio noise absorption (CNA) events associated with equatorward drifting arcs during a substorm growth phase are studied by using simultaneous optical auroral, IRIS imaging riometer and EISCAT incoherent scatter radar ...

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Electric arc I–V modeling and related plasma spectrometry issues
AIP Advances, 2022 This article is devoted to studying the properties of an electric arc column as a development of the authors’ early pioneer experiments. The object of modeling is a free-burning electric arc between evaporating copper electrodes in atmospheric air as the

Advanced Engineering Materials, EarlyView.In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.

Auroral-arc splitting by intrusion of a new convection channel [PDF]
Annales Geophysicae, 1996 During a run of the Common Programme Three of the EISCAT radar the splitting of an auroral arc was observed by high time-resolution, ground-based cameras when the UHF radar beam was close to the arc.

Overview of the arc mechanism and extinguishing in the circuit breaker of a more-electric aircraft
工程科学学报, 2023 A more-electric aircraft refers to an aircraft whose secondary power is unified from the traditional multi-energy, such as mechanical energy, hydraulic energy, and pneumatic energy, to the electrical energy, which has the advantages of a simple system ...

Arc motion and gas flow in current limiting circuit breakers operating with a low contact switching velocity [PDF]
, 2002 Arc motion in low voltage (240 VAC) high current (10/sup 3/-10/sup 4/A.) current limiting-circuit breakers is dominated by arc root mobility. The mobility is influenced by the gas flow and gas composition in the contact region, but there is little ...

Advanced Engineering Materials, EarlyView.Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

The Cathode Drop in an Electric Arc [PDF]
Physical Review, 1929 By making the assumption that the total cathode drop occurs in a distance less than one mean free path from the cathode, Poisson's equation can be solved. If the experimental values of 4000 amperes per square centimeter, and 10 volts are used for the current density at the cathode, and the cathode drop in a mercury arc, values for the electric field ...
