Titanium and titanium alloy have excellent seawater corrosion resistance, high specific strength, non-magnetic, sound transmission, crack resistance and machinability, and its thermal neutron absorption cross section is 56x10-28m2, about 30 times of the wrong. To 1/2. The nuclear properties of titanium alloy are also relatively stable. In the slow neutron flow radiation of 3x10-9~20×10-19, brinell hardness and yield strength increase slightly, while the elongation and resistivity decrease slightly, but the impact toughness does not change, the density of the alloy and the size and shape of the product do not change. Due to these properties, titanium is regarded as an ideal material for ship structure and is known as "ocean metal". The Marine industry of various countries attaches great importance to the application research of titanium and titanium alloy on ships. Special Marine titanium alloy series have been researched and developed, and applied in ships in large quantities to improve the reliability and service life of ship equipment, so as to improve the technical and tactical performance of ships.
Titanium has a wide range of applications in ships, from hull structures, propulsion systems, power systems, electronic information systems and auxiliary systems to special devices. It can be said that titanium and titanium alloy materials can be used in most of the equipment and parts except the ship's accessories and cabin facilities. Therefore, the application prospect of titanium and titanium alloy in ships is very broad, and its application will bring obvious social and economic benefits.
