Problems solved by technology

In the prior art, the protective bracket of such electromagnetic components is usually made of stainless steel. If the magnetic permeability of the stainless steel material is too high, the electromagnetic signal will be easily amplified, resulting in a mismatch between the design signal and the actual transmission signal. If the magnetic permeability of the stainless steel material is to be reduced , then heat treatment is required to transform the internal microstructure of stainless steel into austenite, that is, an additional step of heat treatment is added on the basis of processing to the required size and precision, which not only increases the overall manufacturing cost and process difficulty, but also heat treatment has a negative impact on the metal. Unpredictable material dimensional and magnetic variations add to process unreliability

Abstract

The invention discloses an amorphous alloy support and a preparation method thereof. The support is made of an amorphous alloy. The relative magnetic permeability of the amorphous alloy ranges from 0.99 to 1.02. According to the support, the Vickers hardness is larger than 350 HV, the tensile strength ranges from 2500 MPa to 3000 MPa, and the elastic limit ranges from 1.5% to 3.0%. The thickness of the support ranges from 0.5 mm to 1 mm. The specific strength of the amorphous alloy support is high, and compared with a conventional crystalline-state metal material of the same system, the strength is higher by two times or above. The amorphous alloy support is subjected to forming processing in a hot pressing forming or casting forming manner according to different amorphous alloy systems, aformed blank part can come into service after being subjected to simple trimming treatment, and the subsequent treatment procedure is simplified.

Description

technical field [0001] The invention belongs to the field of amorphous alloy manufacturing, and in particular relates to an amorphous alloy bracket and a preparation method thereof. Background technique [0002] Many of the 3C electronic products in the prior art use bracket structures, such as structural parts in tablet computers and smart phones, for support and protection. At present, the design of 3C electronic products is increasingly developing in the direction of light weight, concentrated functions, and smaller volume. The above-mentioned conventional materials are used as parts for connection, fixing, and support in products, and they must meet the index requirements such as strength and impact performance. Demand, but also as much as possible to make lighter and thinner. The requirement for the bracket structure is to fix, protect, and isolate the parts that need to be connected, but not to be too heavy and take up too much space, and at the same time to be wear-r...
