Abstract

The invention relates to an aluminum-copper-iron quasi-crystal and silicon carbide mixed enhanced aluminum-based composite preparation method. In order to overcome the defects of low tensile strength and low hardness of aluminum-based materials, aluminum alloy serves as a matrix and aluminum-copper-iron quasi-crystal and silicon carbide serve as reinforcing agents to prepare an aluminum-copper-iron quasi-crystal and silicon carbide mixed enhanced aluminum-based composite by means of smelting in a medium-frequency induction melting furnace, argon bottom blowing protection, casting and vacuum heat treatment. The preparation method is technically advanced, precise in procedure and accurate and detailed in data, the aluminum-copper-iron quasi-crystal and silicon carbide mixed enhanced aluminum-based composite prepared according to the method is 80.3HB in hardness which is improved by 50.64%, 285Mpa in tensile strength which is improved by 60.42%, and corrosion resistance is improved by 40%, and the aluminum-copper-iron quasi-crystal and silicon carbide mixed enhanced aluminum-based composite preparation method is pretty optimal.

Description

technical field [0001] The invention relates to a method for preparing aluminum-copper-iron quasi-crystal and silicon carbide mixed reinforced aluminum-based composite material, which belongs to the technical field of non-ferrous metal material preparation and application. Background technique [0002] Aluminum alloy is a non-ferrous metal alloy with good strength, toughness, electrical and thermal conductivity. It is often used as a structural material and has been widely used in aerospace, electronics industry, and automobile manufacturing. Low strength and poor corrosion resistance limit its industrial application. [0003] Quasicrystal materials have the defects of brittleness and loose metallographic structure, so it is difficult to be used as structural materials, but quasicrystals have comprehensive properties of high hardness, non-stickiness, low expansion coefficient, wear resistance, heat resistance, corrosion resistance, and low friction coefficient. It can be us...
