Abstract

The invention provides iron-based amorphous alloy and a preparation method. The iron-based amorphous alloy comprises iron-based metal materials and additives, wherein the iron-based metal materials comprise pure iron, iron-phosphorus intermediate alloy and iron-boron intermediate alloy; the additives comprise boron oxide and soldering flux. SiO2 in the soldering flux reacts with Fe so that beneficial alloy elements can be supplemented into melt. B2O3 covers the surface of the melt to protect the melt, and then the burning loss of the element B and the element P is reduced. Therefore, the contents of the elements in the melt are kept balanced, and the amorphous forming capability and the soft magnetic performance are improved. The iron-based amorphous alloy prepared through the method has relatively high saturation magnetic induction intensity and relatively strong amorphous forming capability, and the saturation magnetic induction intensity can reach 1.7-1.75 T at most.

Description

technical field [0001] The invention relates to the technical field of amorphous alloys, in particular to an iron-based amorphous alloy and a preparation method thereof. Background technique [0002] Amorphous alloy is a solid alloy with a long-range disordered structure obtained when the alloy is solidified by ultra-rapid cooling, and the alloy atoms have no time to arrange and crystallize in an orderly manner. Amorphous alloys do not have the grains and grain boundaries of crystalline alloys. Amorphous alloys have excellent magnetic properties, corrosion resistance, wear resistance, high electrical resistivity, electromechanical coupling, and high strength, hardness, and toughness, so they have broad application prospects. [0003] Iron-based amorphous alloy is one of many amorphous alloys, which has the characteristics of high saturation magnetic induction, magnetic permeability, excitation current and low iron loss. At present, iron-based amorphous alloys are mainly Fe...
