Problems solved by technology

Studies have shown that when the C content is higher than 3at%, the preparation conditions of the alloy are harsh, it is easy to catch fire, the prepared strip is easy to become brittle, and the thermal stability decreases
[0007] In summary, there is still a lack of iron-based amorphous soft magnetic alloys and their products with high saturation magnetic induction and low cost in the market. Therefore, there is still an urgent need for iron-based soft magnetic alloys with high saturation magnetic induction and low cost. Amorphous soft magnetic alloy

Abstract

The invention relates to a novel iron-based amorphous soft magnetic alloy with corrosion resistance and a preparation method thereof. The alloy has an expression of FeaSibBcCdCre, wherein a, b, c, d and e respectively represent the atomic percentage content of corresponding components, a is 80, b is 7.5-9.5, c is 9-12, d is 0.2-2.0, e is 0.1-2.0, and a+b+c+d+e=100. The alloy has high saturated magnetic induction density BS (up to 1.64T), high effective magnetic permeability microE (up to 13096 at 1kHz) and high frequency stability, low coercivity Hc (a minimum of 2.008A / m) and good corrosion resistance, and also has the advantages of good formability, loose preparation process conditions, and low production cost.

Description

technical field [0001] The invention belongs to the technical field of amorphous alloys, and in particular relates to a novel iron-based amorphous soft magnetic alloy with corrosion resistance and a preparation method thereof. Background technique [0002] Amorphous materials belong to the national key new products of the "12th Five-Year Plan" and "13th Five-Year Plan" of the new material industry, and have the remarkable characteristics of green energy saving; especially iron-based amorphous alloys, which have high resistivity and high magnetic permeability, and The loss is very low (only equivalent to 1 / 3~1 / 5 of oriented silicon steel), and compared with silicon steel, the process is simple and no special processing is required, so it is considered to be an ideal core material for power transformers. However, compared with silicon steel, iron-based amorphous alloy still has its disadvantages, that is, the filling factor and saturation magnetic induction are relatively low....
