Abstract

The invention relates to a multicomponent iron-based amorphous soft magnetic alloy. An expression of the alloy is FeaSibBcPdNieCf, wherein a, b, c, d, e and f are atomic percentage contents of corresponding components respectively and meet the conditions that a is 77-82, b is 3-14, c is 8-14, d is 0-0.3, e is 0-2.2, f is 0-2, and the sum of a, b, c, d, e and f is equal to 100. The multicomponent iron-based amorphous soft magnetic alloy has high saturation magnetic induction density Bs, high effective magnetic permeability [mu]e, high frequency stability, low coercivity Hc and low core loss andis good in moldability, loose in preparation technological conditions and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of amorphous alloys, in particular to a multi-element iron-based amorphous soft magnetic alloy. Background technique [0002] Amorphous materials have the remarkable characteristics of green energy saving, and have excellent soft magnetic properties, low loss, which is only equivalent to 1 / 5 to 1 / 3 of silicon steel, but compared with traditional silicon steel, there are still deficiencies, the magnetic properties of silicon steel The saturation strength can reach 2T, but the typical amorphous alloy Fe 78 Si 9 B 13 The magnetic saturation intensity Bs is only 1.56T. More researchers try to increase the magnetic saturation strength of iron-based amorphous soft magnetic alloys. The design of high magnetic induction amorphous alloy composition is mostly based on: (1) increasing the content of iron element and reducing the content of non-ferromagnetic amorphous forming elements (2) adding an appropriate amoun...
