摘要
载人潜水器是探索海底资源、执行多种海底任务的必要设备,载人舱球壳是载人潜水器关键部件,必须使用高比强、高韧性的材料以保证它具有足够的有效载重和良好的安全性。同其它船用金属材料相比,钛合金比强度高,非常适合用于建造潜深3000m以上载人潜水器载人舱球壳,而载人舱球壳用钛合金的发展必将促进我国载人潜水器的研制和国产化进程。总结了目前国内外在载人舱球壳材料方面的研究和应用进展,对国产新型Ti6321合金进行了详细介绍。
Manned deep-ocean submersible is the necessaU equipment for searching resources in seabed and performing benthonic tasks. The manned cabin is the key component of manned deep-ocean submersibles. It is necessary to develop new materials with high strength/density ratio and enough plasticity in order to manufacture high performance manned cabin. Titanium alloys are veU suitable as manned cabin materials beeause of their good properties. Domestic and international progress in research and application of cabin material is summarized; and the newly developed Ti6231 alloy is introduced in particular.
