The low-nickel and low-coercive-force iron-based amorphous soft magnetic alloy material comprises the following components in percentage by weight: 24%-29% of Ni, 3.0%-6.0% of Gd, 1.0%-3.0% of V, 0.01%-0.03% of Hf, 1.0%-3.0% of Al, 0.05%-0.09% of Dy, 0.05%-0.09% of Ta, 0.01%-0.03% of Er and the balance of Fe.

Description

[0001] technical field [0002] The invention belongs to the technical field of metal materials, and relates to a low-nickel and low-coercivity iron-based amorphous soft magnetic alloy material and a preparation method thereof. Background technique [0003] Application No. CN200810231988.7 relates to a forming method of Fe-Ni soft magnetic alloy strip, the steps are as follows: iron and nickel wire are melted into an alloy, and the melted alloy is put into a quartz test tube with holes at the bottom of the vacuum chamber In the process, cycle three times to evacuate and reversely fill high-purity Ar gas; use high-frequency electromagnetic method to heat the fusion alloy, and then fill Ar gas into the quartz test tube to blow the molten sample to the rotating wheel to form a thin alloy strip; The obtained alloy strips were kept at 400° C. for 1 hour under the protection of Ar gas, and then cooled to room temperature with the furnace and released from the furnace. The iron wi...
