Recently, the whole sea deep manned submersible
titanium alloy manned module developed by the institute of metals of the Chinese Academy of Sciences has passed the acceptance inspection.
The all-sea deep manned submersible is one of the first national key research and development projects deployed in China's 13th five-year plan. After its completion, the submersible will carry out manned submersible and scientific research in the ocean covering the world's largest depth (about 11,000 meters), which is the top embodiment of deep sea entry capability. The manned module is the core part of the deep-sea manned submersible, and it is the hardware guarantee and safety barrier for human beings to enter ten thousand meters deep sea. It marks the technical level of a national manned submersible. Full of deep sea manned tank manufacturing is a high performance of titanium alloy design, large thickness plate preparation, hemisphere as a whole, such as big thickness of titanium alloy electron beam welding technology of interdisciplinary systemic engineering, manned space requirement light weight, high strength, weldability and corrosion resistance, fatigue resistance, long life, the material of large size preparation ability and the comprehensive mechanical performance requirements is very high, after is for 3 people, can be used to make the ball tank at home and abroad.
