Abstract

The invention discloses a preparation method of a metal layered composite material by multi-head sleeve drawing composition and belongs to the technical field of preparation of the metal layered composite materials. The preparation method is characterized in that by combination of sheathing two or more than two special metal wires on a metal sleeve, one-pass drawing pre-composition under room temperature, fast heating, single-pass or multi-pass temperature-control drawing metallurgical composition and removal of a metal sleeve layer on the surface, the high-quality special metal layered composite material with all metal components and parallel and non-coincided axis lines can be prepared. The preparation method disclosed by the invention has the advantages that short-process and high-efficiency preparation of the special metal layered composite material is realized, a composite interface with the composite material is high in bonding strength, a diffusion layer is thin, the specification of a product is flexible, the freedom of combination of the materials is large, and the quality and the performance of the product are excellent and the like, the preparation method is especially suitable for preparing a special metal layered composite material with the composite interface and easy generation of intermetallic compounds and a special metal layered composite material with difficulty in processing, and meets the urgent need of all the industries for the special metal layered composite material.

Description

technical field [0001] The invention belongs to the technical field of metal layered composite material preparation, and in particular relates to a method for preparing a metal layered composite material by drawing and compounding a multi-head casing. technical background [0002] Metal layered composite material is a new type of material prepared by using composite preparation technology to make two or more metals with different physical, chemical or mechanical properties be firmly combined on the interface. Although each layer of metal in the metal layered composite maintains its original characteristics, its physical, chemical, and mechanical properties are significantly better than that of a single metal, and it has high strength, corrosion resistance, and good electrical, thermal, and electrical conductivity. Magnetic and other properties, it is widely used in aviation, aerospace, petroleum, chemical industry, automobile, electric power, electronics, national defense an...
