Description

Technical field [0001] The invention relates to the technical field of metals, in particular to a high-strength graphene rare earth aluminum alloy. Background technique [0002] The reserves of aluminum in the earth's crust are extremely rich, accounting for about 7.45% of the total mass of the earth's crust, and its content ranks third after oxygen and silicon. Aluminum alloy has been widely used in aviation, aerospace, construction and other fields because of its good low density, high strength and good processing performance. As a structural material, how to further improve the strength of aluminum alloy is one of the important research directions. The common addition of graphite, silicon carbide, boron carbide, etc. to aluminum alloy to prepare aluminum-based composites has no obvious effect on improving the strength, and affects the aluminum alloy. With the improvement of people’s performance requirements for aluminum alloys, the strength of aluminum alloys needs to be impr...
