Problems solved by technology

Although these two methods are simple in process, the preparation work is cumbersome. It is necessary to ensure that the bonding interface is clean, free from oxidation and appropriate roughness, and the related performance requirements of the laminated rolling material are relatively high. The plasticity of the material should not be too different, otherwise it will be easy. Inadequate welding or cracking leads to poor performance of the material, and the cost of vacuum diffusion welding is relatively high

Description

technical field [0001] The invention belongs to the field of metal material preparation, and in particular relates to a preparation method of a layered aluminum-aluminum matrix composite material plate. Background technique [0002] In order to meet the world's higher demand for lightweight, energy-saving and emission-reducing materials, it is crucial to improve the comprehensive mechanical properties of alloys. Aluminum is the most widely used non-ferrous metal structural material in the industry, and its density is small, only 2.7g / cm 3 , about 1 / 3 of copper or steel. Aluminum matrix composite material is one of the new structural functional materials in the 21st century. It has high specific strength and specific stiffness, good formability, good wear resistance, corrosion resistance and comprehensive mechanical properties. It is widely used in transportation, aerospace , Electronic packaging, sports equipment and other fields. However, the traditional aluminum matrix ...
