Abstract

The invention relates to a preparation method of an iron nickel based soft-magnetic material. According to the preparation method, the iron nickel based soft-magnetic material is prepared from the following alloy materials in atomic proportion: Fe(100-a-b-c-d-e-f)NiaSibAlcCedBeNbf, wherein a=15-20, b=3-4, c=10-15, d=1-2, e=3-5, and f=1-3. The preparation method comprises the following steps: (1) carrying out fusion casting on a mother alloy; (2) preparing an unalloyed strip; and (3) preparing a soft-magnetic material product. According to the soft-magnetic material prepared through the method disclosed by the invention, the magnetic conductivity is enhanced by adopting iron and nickel as main materials; the ductibility of the soft-magnetic material is enhanced by adding higher-proportion aluminum to the soft-magnetic material, so that the mechanical property of the soft-magnetic material is enhanced, and especially the plasticity is enhanced; and the magnetic saturation resistant capacity of the soft-magnetic material is improved by properly adding silicon, cerium, boron and niobium elements.

Description

technical field [0001] The invention relates to a preparation method of an iron-nickel-based soft magnetic material. Background technique [0002] Since its appearance, amorphous soft magnetic alloys have attracted great attention immediately, and have become one of the hotspots in material research in recent decades. Amorphous soft magnetic alloys show good soft magnetic properties due to their irregular arrangement of atoms, aperiodicity, and no grain boundaries, few pinning points or pinning lines of magnetic domains, and small magnetic crystal anisotropy. : Small coercive force, high magnetic permeability, high magnetic induction, high resistivity, low loss, good frequency characteristics. [0003] Compared with Fe-based amorphous alloys, the magnetostriction coefficient and magnetocrystalline anisotropy constant of iron-nickel-based amorphous alloys made with Ni addition are smaller, and the soft magnetic properties are more excellent. Iron-nickel-based amorphous sof...
