Abstract:
A low-loss bulk amorphous metal magnetic component comprising a plurality of substantially similarly shaped layers of heat treated amorphous metal strips having a nanocrystalline microstructure therein, the amorphous metal strips laminated together to form a polyhedrally shaped part wherein said low-loss bulk amorphous metal magnetic component when operated at an excitation frequency â€œfâ€  to a peak induction level Bmax has a core-loss less than â€œLâ€  wherein L is given by the formula L=0.0074 f (Bmax)1.3+0.000282 f1.5 (Bmax)2.4, said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively.
