Agglomeration Behavior of Nonmetallic Particles on the Surface of Si‐Killed Liquid Steel Using HT‐CSLM: An In Situ Investigation

steel research international, EarlyView.
The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

steel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.

Effect of Alloying Mode of Ca-Si Wire and FeS on Morphology of Sulfide in Low Carbon Structural Steel

Teshugang, 2015
The effect of Ca-Si wire and FeS adding sequence on morphology of sulfide and cutting performance of low carbon structural steel (/% ：0.16C, 0.65Mn, 0.25Si, 0.034S, 0.025P) is studied by using a 10 kg induction furnace.

Electronic Modulation of Cobalt Single‐Atom Catalysts via In‐Plane and Axial Coordination Engineering for Enhanced H2O2 Electrosynthesis

SusMat, EarlyView.
Symmetry‐breaking in‐plane and axial coordination modulates the electronic structure of cobalt single‐atom catalysts for selective two‐electron oxygen reduction (2e− ORR). In‐plane O coordination (Co–N2O2) strengthens *OOH binding and suppresses activity, whereas axially coordinated Co–N5 enriches the Co center and optimizes the dz2 orbital, weakening ...

Threshold Currents of Vacuum Arcs With Tungsten and Copper Cathodes

High Voltage, EarlyView.
ABSTRACT This paper presents the results of an experimental study aimed at determining the threshold current for triggering a vacuum arc discharge, the probability of arc ignition and the average arc operation time depending on the current for tungsten and copper electrodes.
