Problems solved by technology

However, limited by the material properties of amorphous iron-based soft magnetic materials, which are hard, brittle, and difficult to cut and level, it is not easy to process, and it is also difficult to cooperate with more complex component magnetic circuit designs.
In addition, since traditional amorphous iron-based soft magnetic materials are generally based on tap casting, there are restrictions on size and thickness.
In addition, there are disadvantages such as high material loss rate and low occupation rate after winding, which greatly limits the application range of amorphous iron-based soft magnetic materials.

Abstract

The present invention discloses a Fe-based amorphous soft magnetic bulk alloy. The Fe-based amorphous soft magnetic bulk alloy has a three dimensional structure which includes a Fe-based amorphous soft magnetic component consisting of FeaCobPcBdSie, wherein a, b, c d and e is the atomic percentage (at %) of each component to meet 76<=a<=80, 1<=b<=4, 9<=c<=11, 3<=d<=5 and 5<=e<=7.

Description

【Technical field】 [0001] The present disclosure relates to a metal soft magnetic material with high magnetic flux density and high magnetic permeability, a preparation method and its application, in particular to a Fe-based amorphous soft magnetic bulk alloy and preparation methods and their applications. 【Background technique】 [0002] An ideal material for making the iron-core of the motor's magnetic components must have high magnetic flux density and high magnetic permeability. Traditionally, silicon steel (silicon steel) is used to make the iron core of the motor magnetic element. However, due to the low sheet resistivity of silicon steel, it can only operate under low frequency DC and AC. When the operating frequency increases, the eddy current loss of the silicon steel sheet core will increase sharply, resulting in a decrease in energy conversion efficiency. In order to prevent the generation of eddy currents or reduce the energy loss caused by eddy currents, the ex...
