Reinforced composite metal structure and moulding method and application thereof

Abstract

The invention discloses a reinforced composite metal structure. The reinforced composite metal structure comprises a main body metal structure and a reinforcing component; the reinforcing component isconnected with the main body metal material in an embedded, externally-wrapping, penetrating, partially-connection or transition-connection mode; the reinforcing component comprises one or more reinforcing structural elements; a part, which is embedded the main body metal structure, of each single reinforcing structural element accounts for 5-100% of the reinforcing structural element; and each reinforcing structural component has a matched preset shape according to features of the main body metal structure, and is arranged at a partial zone, which needs to be reinforced, in the main body metal structure. According to the reinforced composite metal structure, a mode of embedding the prefabricated reinforcing components is adopted, so that the prefabricated reinforcing components are deeply combined with an amorphous alloy base body; when a products adopting the mode is encountered with a force generated by bending or impacting, a mutual supporting structure is formed by the prefabricated reinforcing components and the amorphous alloy base body; and in an elastic range of the amorphous alloy base body, double protection is formed for electronic elements or other parts in the product.

Description

technical field [0001] The invention belongs to the field of metal composite materials, and in particular relates to a composite metal structure with reinforcing function and a forming method and application thereof. Background technique [0002] Metal material is one of the most commonly used materials in national production and life. It has the advantages of high strength, high hardness, and good appearance and texture. It has a very wide range of applications in the fields of construction, military industry, aerospace, 3C electronics, and daily necessities. Amorphous alloy material is a new type of metal material that has developed rapidly in recent years. It has high specific strength, specific modulus, high hardness, wear resistance and corrosion resistance. It has been used in aerospace, automotive sports products, consumer electronics. It has been applied in other fields and attracted more and more attention. However, due to the unique microstructure characteristics ...

Problems solved by technology

[0004] Although the above technical solutions have been disclosed in many documents and patents, and many researchers have made more detailed improvements to them, such as adding connection structures, they have not been widely used in actual manufacturing technology. The reason is that the distribution uniformity of the endogenous strengthening phase in the above technology is difficult to control due to the difference in the cooling rate of each part of the product. It is difficult for the phase to bear the stress uniformly, resulting in inconsistent strain levels and easy to cause fracture.

In view of the above insurmountable shortcomings, some relevant surface stress treatment and surface coating technical solutions have also been proposed, both of which form a deformation-resistant structure on the surface of the amorphous alloy, in order to offset the hot compressive stress and reduce the pressure on the internal surface. However, in the actual fracture mode of the product, the technical effects of surface stress treatment and surface coating are very limited, and surface stress treatment and surface coating structure are new processes, which have greatly improved after the increase. The difficulty of the overall process, which directly increases the cost of the prepared product, further limits the application of this technology
