Description
Technical Field
The invention belongs to the field of manufacturing of wrought aluminum alloy, and particularly relates to high-brightness aluminum alloy for an automobile door and window trim and a preparation method of the high-brightness aluminum alloy.
Background
The aluminum alloy serving as a current lighter structural material has the advantages of low density, high specific strength and specific stiffness, good damping and shock absorption, excellent electromagnetic shielding performance, easiness in recovery and the like, and has important application in the fields of aerospace, automobiles and 3C. The mechanical properties of aluminum alloys are much lower than steel materials, limiting their application to many industrial devices and products. In order to expand the application range and field of the aluminum alloy, research and research work is carried out on the existing aluminum alloy in a large quantity, and although many research and research works carry out many modifications on the existing aluminum alloy, the applicability is not ideal. The addition of a small amount of rare earth elements can obviously refine the grains of the aluminum alloy casting structure, but the aluminum alloy casting structure contains more structure defects such as: shrinkage porosity, shrinkage porosity and inclusions, resulting in poor mechanical properties. Compared with a cast aluminum alloy, the wrought aluminum alloy obtained by extrusion, forging and rolling has a more compact and uniform structure; and the addition of a small amount of rare earth elements can promote dynamic recrystallization and activate non-basal plane slippage in the thermal deformation process, so that the grain size is refined, the basal plane texture is weakened, and the plasticity of the aluminum alloy is improved. Although the mechanical property of the existing high-content rare earth aluminum alloy can be improved, the technical process for improving the brightness of the alloy is rare.
In order to improve the brightness of aluminum alloys, it is common in the industry to add a large amount of rare earth elements to the selection of alloying elements to obtain high strength aluminum alloys. The high-strength aluminum alloy adopts rare earth elements with higher content, the rare earth elements are high in cost, the cost of the aluminum alloy is greatly increased, the specific gravity is high, the advantage of light weight of the aluminum alloy cannot be fully exerted, and the requirement of large-scale industrial production cannot be met.
