The core-shell structured Fe-based amorphous magnetic powder cores with excellent magnetic properties

Advanced Powder Technology, 2019
Abstract The Fe-based soft magnetic amorphous powder cores (AMPCs) with excellent comprehensive magnetic properties were successfully designed and fabricated using the core-shell structured FeSiBCCr/TiO2 composite powders. The influence of the concentration of water (H2O) for the magnetic performance of the AMPCs has been systematically studied based

Preparation of amorphous Fe-based magnetic powder by water atomization

Powder Technology, 2011
Abstract Fe–Si–B–C–P amorphous powders were fabricated successfully by water atomization. The morphology, chemical composition, phase structure and soft magnetic properties were then studied in this work. The results indicate that the powders are completely amorphous in nature.

Powder Injection Molding of Cu-Based Amorphous Powders and Fe-Based Metamorphic Powders

ASME 2008 2nd Multifunctional Nanocomposites and Nanomaterials, 2008
Powder injection molding (PIM) process was applied to Cu-based amorphous alloy powders and Fe-based metamorphic alloy powders, and microstructure, hardness, and wear resistance of the PIM products were analyzed. When Cu-based amorphous powders were injection-molded and sintered at 470 °C, sintering was not made since most of amorphous phases were ...

Preparation of new amorphous powder cores using Fe-based glassy alloy

INTERMAG 2000 Digest of Technical Papers. 2000 IEEE International Magnetics Conference, 2000
So as to obtain a new metallic powder core with constant permeability and low core loss up to higher frequency range, we have tried to prepare the amorphous alloy powder cores by using the Fe/sub 70/Al/sub 5/Ga/sub 2/P/sub 9.65/C/sub 5.75/B/sub 4.6/Si/sub 3/ glassy alloy powders that have a wide supercooled liquid region (/spl Delta/T/sub x/) below the

Novel Fe-based amorphous magnetic powder cores with ultra-low core losses

Science China Technological Sciences, 2010
Amorphous magnetic alloy powders were prepared from bulk metallic glasses Fe74Cr2Mo2Sn2P10Si4B4C2 with supercooled liquid region of 32 K by water atomization. Amorphous magnetic powder core precursor was produced from a mixture of the amorphous alloy powder with addition of insulation and bonding materials by mold compacting at room temperature.

Magnetic Properties of Fe-Based Amorphous Powder Cores With High Magnetic Flux Density

IEEE Transactions on Magnetics, 2009
Fe81(Si0.3B0.7)17C2 amorphous powder cores with glass binder were fabricated by compact-pressing techniques, and the relation between magnetic properties and powder particle sizes was evaluated. The Fe81 (Si0.3B0.7)17C2 powder core exhibited superior magnetic properties compared with our previously developed (Fe0.97Cr0.03)76 (Si0.5 B0.5 )22C2 powder ...
