Fabrication and Magnetic Properties of A New Fe-based Amorphous Compound Powder Cores [PDF]

open access: yesJournal of Magnetics, 2011
A new Fe-based amorphous compound powder was prepared from Fe-Si-B amorphous powder by crushing amorphous ribbons as the first magnetic component and Fe-Cr-Mo metallic glassy powder by water atomization as the second magnetic component. Subsequently by adding organic and inorganic binders to the compound powder and cold pressing, the new Fe-based ...
