Research and Development Progress of Metal Materials for Manned Submersible Pressure Hulls

The current status of material selection of pressure hulls for manned submersibles with working depths of more than 6 000 m above at home and abroad is introduced. By studying the application of metal materials for manned submersibles in various ocean powers, the research and development progress of the metal materials for manned submersible pressure hulls is reviewed, and the development trend of the technology is analyzed.
