Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific examples.

[0026] A soft magnetic material, which comprises the following components in terms of weight percentage:

[0027] Pd 0.3-0.6%, Ni 0.8-1.2%, In 0.2-0.6%, Ga 0.05-0.08%, Ge 0.2-0.5%, Be0.03-0.06%, Ce 0.01-0.05%, Au 0.003-0.006%, Si 2-5%, B 1-3%, Fe balance.

[0028] The specific process of the preparation process is as follows:

[0029] First carry out batching according to above-mentioned alloy composition, the purity of Pd, Ni, In, Ga, Ge, Be, Ce, Au, Fe in the raw material is all greater than 99.9%; B is added in the form of boron-iron alloy, wherein the weight percentage of B is 24% %;

[0030] The raw materials are melted in a vacuum induction furnace at a melting temperature of 1480-1500°C to obtain a master alloy, which is then put into a remelting tubular crucible in a vacuum induction forming furnace for remelting at a remelting temperature of 1500-1520°C; There is ...

Abstract

The invention relates to a soft magnetic material and a preparation method thereof. The soft magnetic material comprises the following constituents based on percent by weight: 0.3-0.6% of Pd, 0.8-1.2% of Ni, 0.2-0.6% of In, 0.05-0.08% of Ga, 0.2-0.5% of Ge, 0.03-0.06% of Be, 0.01-0.05% of Ce, 0.003-0.006% of Au, 2-5% of Si and 1-3% of B with the balance being Fe. According to the method, a mode combining rapid cooling, thermal processing and alloying is employed in alloy solidification during the preparation process, the uniformity of alloy constituents, organization and performance is ensured, and the alloy quality is ensured. The alloy is simple in preparation technology and process, the produced alloy has favorable performance, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the field of functional materials, in particular to a soft magnetic material and a preparation method thereof. Background technique [0002] At present, the soft magnetic materials in the prior art still have defects in their properties. For example, the invention patent with the patent application number CN201610855274.8 discloses a heat treatment method for preparing thin strips by rapid solidification and stripping method. According to the application conditions, an appropriate heat treatment process is proposed. For iron cores without toughness and plasticity requirements, anneal in a bell furnace under vacuum or hydrogen atmosphere, and slowly cool with the furnace to make iron cores with excellent soft magnetic properties; for iron cores with toughness and plasticity The required iron core is treated at high temperature in a hydrogen atmosphere for a short time in a continuous heat treatment furnace, and then air-cooled a...
