Physical Modeling of Core Losses in Ferrite E-Cores
IEEE Open Journal of Power ElectronicsThe development of advanced power electronic converters requires an accurate calculation of core losses in magnetic devices. But the losses in the widely used ferrite cores depend on the shape of the core, especially above 10 kHz, meaning that core ...

The Combined Influence of Molybdenum and Nickel in Steel Welds [PDF]
Archives of Metallurgy and Materials, 2018 Weld metal deposit (WMD) was carried out for standard MMA welding process. This welding method is still promising mainly due to the high amount of AF (acicular ferrite) and low amount of MAC (self-tempered martensite, retained austenite, carbide) phases ...

Synthesis and evaluation of nickel cobalt ferrite magnetic ceramics employing two alternative routes
Journal of Advanced Dielectrics, 2021 Ni0.5Co0.5Fe2O4 (NCF) powders were obtained employing two alternative synthesis routes: solid-state reaction and Pechini’s methods. The ceramic powders were pressed and sintered in the temperature range of 1100∘C to 1250∘C. Microstructural and structural
