Abstract

The invention discloses a method for manufacturing a multilayer amorphous alloy and copper composite structure through intermediate layer diffusion. The method includes the steps of cutting, grinding, polishing and cleaning an amorphous alloy sheet and a copper sheet; dividing an intermediate layer into a predetermined size with a blade; assembling and fixing the amorphous alloy sheet, the intermediate layer and the copper sheet for forming a fixed workpiece; placing the fixed workpiece in a vacuum diffusion furnace for enabling the intermediate layer to be dissolved in the amorphous alloy sheet and the copper sheet for further achieving diffusion welding. According to the method for manufacturing the multilayer amorphous alloy and copper composite structure through intermediate layer diffusion, the diffusion temperature can be reduced through the intermediate layer so as to enable the amorphous alloy sheet to maintain an amorphous state. The composite structure has the strength of the amorphous alloy and the toughness of the copper and can block the extension of a shear band in plastic deformation of the amorphous alloy, so that the problem of brittle failure easiness of pure amorphous alloy can be avoided, the anti-shear ability can be enhanced, the surface of the welded sheet is high in quality, and the connection is reliable.

Description

technical field [0001] The invention belongs to the field of diffusion welding, and more specifically relates to a method for preparing a multilayer amorphous alloy and copper composite structure by using intermediate layer diffusion. Background technique [0002] Amorphous alloys are a major discovery in the field of materials in the 20th century. The atomic arrangement inside the material is a long-range disordered short-range order structure, without defects such as dislocations and grain boundaries. This unique structure makes amorphous alloy materials have many excellent properties, such as high strength, hardness, wear resistance, corrosion resistance, excellent soft magnetic properties, etc., in military, micro / nano manufacturing, sports equipment, optical communications, Optical integration, lasers, new solar cells, high-efficiency magnetic and power transmission materials have broad application prospects. Amorphous alloys are promising new structural materials and ...
