Abstract
The invention discloses a bulk iron-based amorphous alloy material. The bulk iron-based amorphous alloy material is characterized in that a general formula of the bulk iron-based amorphous alloy material is FeaBbYcNbdTie, wherein in the formula, a is not smaller than 65 and not greater than 75, b is greater than 15 and smaller than or equal to 25, c is greater than 0 and smaller than or equal to 5, d is greater than 0 and smaller than or equal to 5, and e is smaller than or equal to 5, wherein a, b, c, d and e are atomic percents of corresponding elements in the alloy and meet the relationship that the summation of the a, the b, the c, the d and the e is equal to 100. According to the bulk iron-based amorphous alloy material disclosed by the invention, sponge titanium with low price is used to replace expensive high-purity metal niobium, so the production cost is greatly reduced; besides, the bulk iron-based amorphous alloy material has the characteristics of simple preparation process, strong forming capability of the amorphous alloy, excellent thermal stability and mechanical property and good magnetic performance.
Description
technical field [0001] The metal material of the invention belongs to the field of amorphous alloys, and in particular relates to a novel iron-based amorphous alloy material with good soft magnetism, high mechanical strength and large amorphous forming ability, which is applied to soft magnetic materials and structural materials. Background technique [0002] Iron-based amorphous alloy is one of the most widely used amorphous alloys at present. Compared with other systems of amorphous alloy materials, the cost of raw materials is low, and it has high strength, high hardness, good corrosion resistance, and high heat dissipation. Stability, excellent soft magnetic properties, has received extensive attention. However, the low amorphous-forming ability makes this type of alloy only appear in the form of thin strips, wires, or powders, which affects its application range to a certain extent. In 1995, Akihisa Inoue and others successfully prepared Fe-(Al,Ga)-(P,C,S,B) iron-based...
