INFLUENCE OF PLASTIC DEFORMATION CARBON STEEL ON THE PROCESS OF BURNING ELECTRIC ARC [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2021
During a study of the combustion process of a direct polarity electric arc, a directly proportional dependence of the electric current value on the degree of cold plastic deformation of carbon steel used as an electrode was found.

Preparation and electrical properties of dense micro-cermets made of nickel ferrite and metallic copper [PDF]

open access: yes, 2009
Dense micro-cermets made of nickel ferrites and copper micrometric particles were obtained from partial reduction under hydrogenated atmosphere at 350 C of mixed copper nickel ferrites, and sintering in nitrogen at 980 C.

Eigen electric moments of magnetic-dipolar modes in quasi-2D ferrite disk particles [PDF]

open access: yes, 2007
A property associated with a vortex structure becomes evident from an analysis of confinement phenomena of magnetic oscillations in a quasi-2D ferrite disk with a dominating role of magnetic-dipolar (non-exchange-interaction) spectra.

A Low-Profile Ferrite Dipole VHF Antenna for Integrated Mast Applications

open access: yesApplied Sciences, 2020
In this paper, an extremely low-profile ferrite dipole antenna operating on the VHF band (30−300 MHz) is proposed. The design antenna consists of 44 plate-type ferrite cells arranged into two stacked ferrite layers: a bottom ferrite layer with ...

Shear-induced α → γ transformation in nanoscale Fe-C composite [PDF]

open access: yes, 2006
High-resolution transmission electron microscopy and three-dimensional atom probe observations show clearly that a reverse transformation of body-centred cubic ferrite to face-centred cubic austenite occurs during severe plastic deformation of a ...

Synthesis of Spinel Ferrite MFe2O4 (M = Co, Cu, Mn, and Zn) for Persulfate Activation to Remove Aqueous Organics: Effects of M-Site Metal and Synthetic Method

open access: yesFrontiers in Chemistry, 2020
Metal species and synthetic method determine the characteristics of spinel ferrite MFe2O4. Herein, a series of MFe2O4 (M = Co, Cu, Mn, Zn) were synthesized to investigate the effect of M-site metal on persulfate activation for the removal of organics ...
