Problems solved by technology

However, due to the high melting point and low density of carbon, it is not easy to add in direct smelting, and the content is not easy to control
[0004] It can be seen that too many components will make it difficult to control the composition during smelting, and the content of each component can affect the amorphous forming ability and soft magnetic properties of the alloy, which is unfavorable for the control of the composition stability of the product

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to an iron-based soft magnetic amorphous alloy with few components, low cost and high saturation magnetic induction and its preparation process. Background technique [0002] There are no high-cost niobium, zirconium, molybdenum, rare earth and other elements in Fe-X (X is metalloid B, Si, P, C, etc.) amorphous alloys, only low-cost Fe-P, Fe-B, Fe- C. Fe-Si master alloy is made by melting and throwing process. It is a metal magnetic functional material with excellent comprehensive performance. It is widely used in power transmission and distribution, electronic information, new energy vehicles and other industries to meet the major needs of energy conservation and emission reduction in my country. However, compared with silicon steel, the current iron-based amorphous has a lower saturation magnetic induction intensity, resulting in a larger volume of amorphous products, inc...
