Abstract

Magnetic properties of nanocrystalline Fe90-xZr7B3Nix (x = 2-4) melt-spun ribbons and consolidated bulk alloys have been investigated. The magnetostriction of Fe90-xZr7B3Nix ribbon changed from - 1.8 × 10-6 to 1.8 × 10-6 when x changed from 0 to 4 and became zero at x = 1.5. Soft-magnetic properties of ribbon and consolidated bulk Fe90-xZr7B3Nix were better than those of Fe90Zr7B3. Nanocrystalline Fe86Zr7B3Ni4 consolidated bulk with grain sizes of 10-20 nm exhibited magnetic flux density of 1.55 T, maximum permeability of 23000, effective permeability of 3360 at 300 Hz, and coercivity of 14 A/m.
