Problems solved by technology

The molding preparation of this material requires solid solution and aging heat treatment. These two treatments take a lot of time and high energy consumption, which affects production efficiency; at the same time, solid solution heating and aging treatment will reduce the rolling capacity of alloy or metal matrix composite materials The elongation performance of the finished sheet is usually less than 2%. The plasticity of the sheet is poor, and it is prone to breakage when the force is uneven, especially for parts such as automobiles, rail transit, and aerospace. There are high requirements on the strength and toughness of the plate to ensure its safety in use. Therefore, this defect limits its further development
