Embodiment 1

[0025] An FeBC soft magnetic amorphous alloy is composed of iron, boron and carbon elements. The atomic percentages of the elements in the alloy are as follows: 8% boron, 9% carbon, and 83% iron.

[0026] The preparation steps are as follows:

[0027] (1) The raw materials are pure iron (99.9%), industrial grade iron-carbon alloy (carbon mass percentage is 4.2%), industrial grade iron-boron master alloy (B mass percentage is 18.9%);

[0028] Use a balance to weigh the raw materials according to the atomic percentages of Fe83%, B8%, and C9%, which are Fe: 5.59g, Fe-C master alloy: 7.99g, Fe-B master alloy: 1.42g;

[0029] (2) Put the raw materials into the glass tube in the vacuum induction melting furnace, and use a mechanical pump and a molecular pump to evacuate to 2×10 - 3 Pa, filled with high-purity argon for arc smelting; after smelting, take it out and smash it to check whether there are unmelted raw materials, and if there are unmelted materials, carry out the second ...

Abstract

The invention relates to a FeBC soft magnetic amorphous alloy with few components, low cost and high saturation magnetic induction strength and a preparation process thereof. The atomic percent of elements in the FeBC soft magnetic amorphous alloy are as follows: 6% <= boron <= 13%, 5% <= carbon <= 12%, 80% <= iron <= 86%. The FeBC soft magnetic amorphous alloy is low in production cost and simplein process. The prepared soft magnetic amorphous alloys have the characteristics of high saturation magnetization intensity and low coercivity, and are suitable for transformer cores, amorphous motors and other devices, as well as for power, electronics, information, communication and other fields.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a FeBC soft magnetic amorphous alloy with few components, low cost and high saturation magnetic induction and a preparation process thereof. Background technique [0002] Fe-X (X is metalloid B, Si, P, C, etc.) amorphous alloy is a soft magnetic material with excellent comprehensive performance. It is widely used in power transmission and distribution, electronic information, new energy vehicles and other industries to meet my country's energy-saving Significant need to reduce emissions. However, the saturation magnetic induction of FeSiB amorphous produced at present is low, and its application is limited. Through suitable compositional design, currently in FeBSiP and Fe 83 (BSiPC) 17 Both have obtained excellent soft magnetic properties, but these excellent soft magnetic properties are obtained by using high-purity Fe-P master alloy, and the cost is too high, which ...
