Iron-base amorphous alloy material with high saturation magnetic induction density

Abstract

The invention discloses an iron-based amorphous alloy material with high saturation magnetic induction. The chemical composition of the iron-based amorphous alloy material is FeaMobSicPdCeBf, and a+b+c+d+e+f=100%, the atoms of b The percentage range is 0-2, the atomic percentage range of c is 2-5, the atomic percentage range of d is 8-10, the atomic percentage range of e is 5-8, the atomic percentage range of f is 3-5, a is the rest quantity. The FeaMobSicPdCeBf alloy material of the invention has a high saturation magnetic induction of 1.30-1.55T and good amorphous forming ability, and can be widely used in structural materials and soft magnetic materials. The preparation method of the alloy material is simple and the production cost is low.

Description

technical field

[0001] The invention relates to a novel iron-based amorphous alloy material with high strength, toughness, soft magnetism and good forming ability, which is mainly used in structural materials and soft magnetic materials. Background technique

[0002] The amorphous alloy prepared by rapidly solidifying the alloy composition from the gaseous or liquid state forms a special amorphous structure because it does not have long-range atomic order. This amorphous structure leads to the unique mechanical properties and magnetic properties of the amorphous alloy. , corrosion resistance and electrical properties, so it has become a very important field in material research.

[0003] As we all know, the current soft magnetic materials have a high saturation magnetic induction B S The material is silicon steel, its B S The value can reach 2T, but the coercive force Hc of silicon steel material is very high, and the loss is large; while the cobalt-based amorphous materia...
