Problems solved by technology

However, iron-based amorphous alloys lack the ability to deform macroscopically at room temperature, are highly brittle, and are prone to brittle fracture, which affects their engineering applications as structural materials. Lead to unfavorable phenomena such as incomplete magnetic circuit and transformer breakdown

Abstract

The invention provides an amorphous alloy with favorable toughness and a preparation method thereof, and belongs to the technical field of magnetic material preparation. The amorphous alloy is prepared from the following element components in percentage by mass: 2.5 to 7.5 percent of Ni, 8.2 to 10.5 percent of Si, 1.5 to 3.8 percent of B, 1.0 to 1.7 percent of Mn, 1.3 to 2.0 percent of Sn, and thebalance Fe. Through optimizing the alloy element components and the matching ratio and adopting an annealing process, the amorphous alloy product with an excellent soft magnetic performance and favorable toughness is obtained.

Description

technical field [0001] The invention relates to the technical field of magnetic material preparation, in particular to an amorphous alloy with good toughness and a preparation method thereof. Background technique [0002] Iron-based amorphous alloy is a new type of material developed in the 1960s. Compared with traditional steel, it has an atomic structure with long-range disorder and short-range order in structure, without defects such as grain boundaries and dislocations; in terms of chemical composition, element distribution Uniform, no segregation and other phenomena; with high saturation magnetic induction, low coercive force, low loss and other excellent properties, it is widely used in transformers, motors, reactors, transformers, mutual induction coils and other fields. However, iron-based amorphous alloys lack the ability to deform macroscopically at room temperature, are highly brittle, and are prone to brittle fracture, which affects their engineering applications...
