Abstract

The invention provides a Fe-Si-B amorphous alloy-copper laminated composite material and a preparation method thereof. A vacuum diffusion connection testing machine is used, and Fe-Si-B amorphous alloy and copper are welded to form the laminated composite material through a diffusion welding method. In preparation, at super-cooled liquid-phase region temperature of the amorphous alloy, plastic deformation is performed on the amorphous alloy and the copper through pressure effect, connection surface oxidation films are removed, fresh surfaces of the amorphous alloy and the copper are contacted tightly, connection interface diffusion process is promoted through thermal insulation and pressure maintaining simultaneously, and an iron-based amorphous-copper laminated composite material of a large size is prepared under the precondition that crystallization of the amorphous alloy is avoided. By adopting the technical scheme, process parameters are controlled strictly and accurately, and the large-size composite material with good connection performance and broadband shielding performance is obtained.

Description

technical field [0001] The invention relates to the field of composite material preparation, in particular to a preparation method of Fe-Si-B amorphous alloy-copper layered composite material. Background technique [0002] Metallic glass has more excellent properties than conventional crystalline metals, such as high strength, high toughness, good wear resistance and corrosion resistance, excellent magnetic properties, etc. Since the 1860s, when Professor Duwez of Caltech first prepared the amorphous Au-Si alloy, metallic glass has been a hot research field of scientists from all over the world. Some developed countries such as the United States and Japan have invested a lot of money to develop the application of amorphous alloys in national defense and aerospace. For example, the solar wind collector made of Zr-based amorphous in the United States has successfully collected high-energy solar wind ions. The armor-piercing ability of the armor-piercing projectile is also sig...
