Aluminum Matrix Composite

Abstract

The invention provides an aluminum-based composite material. The aluminum-based composite material comprises a basal body and a reinforced material, wherein the basal body is pure aluminum; the reinforced material is distributed in the basal body. The reinforced material is combined with the basal body in a solid state, and a compound formed by the pure aluminum in the aluminum-based composite material and the reinforced material accounts for 0.001 percent of the aluminum-based composite material in volume fraction. The solid-state combination is actually a solid-state welding or seaming process, which is a physical process. In the solid-state welding process, the basal body pure aluminum is only just subjected to plastic deformation, the pure aluminum subjected to the plastic deformation covers the reinforced material, is fully mixed with the reinforced material to obtain a mixture, and then is integrally combined with the reinforced material after the mixture is cooled, and therefore, the aluminum-based composite material with excellent mechanical property and high conductivity is obtained. In addition, chemical reaction between the basal body and the reinforced material is avoided or slight chemical reaction between the basal body and the reinforced material is carried out, even if certain compounds are produced, the contents of the compounds are also extremely few, and influence on comprehensive performance of the aluminum-based composite material is small, even can be omitted.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to an aluminum-based composite material. Background technique [0002] With the rapid development of modern science and technology and industrial manufacturing, fields such as aerospace, vehicle engineering, and power electronics have put forward higher requirements for the mechanical properties and electrical conductivity of metal materials. On the basis of improving the mechanical properties of metal materials, especially the tensile strength and ductility, maintaining or even improving their electrical conductivity has gradually become a research hotspot in these fields in recent years. [0003] As a metal material, pure aluminum has good electrical conductivity, which can basically meet the requirements for the electrical conductivity of metal materials in the above fields. However, the tensile strength of pure aluminum itself is low, and while the tensil...

Problems solved by technology

However, the tensile strength of pure aluminum itself is low. While increasing the tensile strength of pure aluminum, its electrical conductivity will inevitably be significantly reduced due to the incorporation of reinforcing materials (ie, reinforcing phases).
