Abstract

The invention relates to a method for preparing a multi-component synergistically strengthened aluminum-based composite material. Aiming at the poor mechanical properties of cast aluminum-lithium alloys, different alloy elements and endogenous titanium carbide phases are added to the aluminum-lithium alloys, and the aluminum-lithium alloys are smelted. , argon bottom blowing, electromagnetic stirring, extrusion casting and heat treatment to make a multi-component synergistically strengthened aluminum matrix composite; Up to 485MPa, hardness up to 189Hv, is an advanced multi-component synergistically strengthened aluminum matrix composite material preparation method.

Description

technical field [0001] The invention relates to a method for preparing a multi-component synergistically strengthened aluminum matrix composite material, which belongs to the technical field of nonferrous metal composite material preparation. Background technique [0002] In the history of aerospace development, the requirements for fuselage structural materials have hardly changed, and materials with high strength, low density and high stiffness are still the first choice. However, every 1.0wt% Li added to the aluminum alloy can reduce the density of the final formed aluminum alloy by about 3%. Therefore, aluminum-lithium alloys with the characteristics of low density, high specific strength, high elastic modulus, good corrosion resistance, and good processing and molding have been widely used in the aerospace field. Among them, the cast aluminum-lithium alloy can have a relatively high Li content, and there is no serious anisotropy problem, and can be used to prepare comp...
