Ti合金作为一种质轻、高强、耐腐蚀的优异轻型结构材料，能够显著提升舰船装备技战术性能，增强海洋安全保障能力。目前，舰船用Ti合金材料技术主要集中在俄、美、法、日、中等国家，其中俄罗斯、美国和法国在军用舰船用Ti的研究和应用方面处于世界领先水平，而日本的民用舰船用Ti合金方面已经进行了很好的尝试。文献资料表明， Ti合金在舰船上主要用来制造耐压壳体、热交换器、冷凝器、核反应堆外壳以及配套管道系统，未来Ti合金在使用量和使用部位上还将会不断扩大，新的先进加工成形技术及焊接技术仍将得到充分重视，大力降低Ti合金部件的制造成本是目前国外发展的重点方向。近年来我国Ti工业得到了迅猛的发展，材料加工和成形技术以及装备水平得到了很大的提高，而且Ti合金成本也降到了历史最低水平，为Ti合金在舰船上的应用带来了良好的机遇。因此，我国应充分重视“海洋金属”Ti在舰船乃至海洋重要工程装备上的应用研究和技术发展，以创新和超越的思路与理念为舰船提供安全性、可靠性和全寿命的保障，为实现海洋强国的战略目标及海洋经济创新发展提供重要的物质支撑。

As a lightweight,high strength,excellent corrosion resistance structural materials,titanium can significantly improve the technical and tactical performance of ships equipment,and enhance life-time security capabilities.Currently, titanium alloy and its manufacture technologies for ships utilization are mainly concentrated in Russia,the United States, France,Japan,China etc.Russia,the United States and France have made remarkable progress known in titanium re-search and applications for warships,and Japan is well known by titanium applications in civil ships.Literature shows that titanium and titanium alloys are mainly used for shell,heat exchanger,condensers,nuclear reactors shell as well as piping systems.Titanium and titanium alloy used for ships will continue to expand in the future,and some new advanced proces-ses and technologies will be paid much more attention in order to reduce the cost of titanium parts manufacturing.In recent years,Chinese titanium industry has made a great development,and titanium manufacture processes and forming technolo-gies as well as its equipment levels have greatly improved,and also the cost of titanium alloy has dropped to historic lowest point,that provides the massive application of titanium alloy in ship with a great opportunity.We should pay sufficient at-tentions to research and development of titanium alloy,which was called “Marine Metal”,and try to give a strong support to the safety,reliability and security of the ships during its whole life.
