Problems solved by technology

[0003] Due to the low cost of iron, the current research on iron-based amorphous soft magnetic alloys is more popular, but in terms of the results obtained at this stage, the effects are not ideal, and its amorphous formation ability is somewhat improved when the maximum saturation magnetic induction is increased. Decrease, or its maximum saturation magnetic induction decreases when the amorphous formation ability is improved

Abstract

The invention provides an iron-based amorphous soft magnetic alloy and a preparation method thereof. The iron-based amorphous soft magnetic alloy has a molecular formula of FeaSibBcCxYd. The preparation method comprises the steps of arranging raw materials; smelting the prepared raw materials in a smelting furnace, and leading a smelted melt to a heating device; connecting the heating device witha spray bag; pouring, by the heating device, the melt from a spray bag funnel onto the surface of a copper roll through the spray bag, such that the melt is rapidly cooled after being in contact withthe copper roll and a strip sample is formed to obtain the iron-based amorphous soft magnetic alloy. The iron-based amorphous soft magnetic alloy provided by the invention successfully improves the magnetic properties of the alloy under the condition of ensuring a good amorphous forming ability.

Description

technical field [0001] The invention relates to the technical field of magnetic functional alloys, in particular to an iron-based amorphous soft magnetic alloy and a preparation method thereof. Background technique [0002] Soft magnetic alloy refers to an alloy that can quickly respond to changes in the external magnetic field, and has the characteristics of low loss, high saturation magnetic induction, low power loss, and good working stability. The development of soft magnetic alloys has gone through the development process of electrical pure iron, silicon steel materials, permalloy, ferrite materials to amorphous magnetic alloys. Although silicon steel materials and ferrite materials still account for the main part of soft magnetic alloys, the iron loss of silicon steel materials is relatively large, while the saturation magnetic induction of ferrite materials is low. [0003] Due to the low cost of iron, the current research on iron-based amorphous soft magnetic alloys...
