【摘要】 钛具有比强度高、耐腐蚀、耐高温、无磁等特点，特别是具有良好的耐海水和海洋大气腐蚀性能，是理想的海洋工程用材料，被誉为“海洋金属”。我国从20世纪60年代开始开发舰船用钛合金，形成了不同强度级别的钛合金牌号，在能源开采装备用钛材的研究和应用方面起步较晚，目前仍处于起步阶段。随着建设海洋强国战略的提出，我国海洋发展从浅海走向深海、远海，钛及钛合金在海洋工程领域应用的优势更加凸显出来。从舰船用钛合金和能源装备用钛合金两个方面介绍了我国海洋工程领域用钛合金材料的研究现状，简述了海洋工程领域用大规格钛合金铸锭及构件制备技术、低成本制备技术及能源开采装备用钛合金无缝管材制备技术等方面的研究进展，并提出了目前存在的主要问题，以期为舰船及能源装备用钛合金材料及其构件制备技术的研究提供参考。更多还原

【Abstract】 Titanium has the characteristics of high specific strength, corrosion resistance, high temperature resistance and non-magnetic properties, especially good resistance to seawater and marine atmospheric corrosion. It is an ideal material for marine engineering and is known as the “marine metal”. China began developing titanium alloys for ships in the 1960s, forming titanium alloy grades with different strength levels. The research and application of titanium materials for energy extraction equipment started relatively late and is still in its infancy at present. With the proposal of maritime power strategy, the country’s marine development is advancing from shallow to deep and distant seas, further highlighting the advantages of titanium and titanium alloys in marine engineering applications. This article introduces the current research status of titanium alloy materials used in the field of marine engineering in China from two aspects: titanium alloys for ships and titanium alloys for energy equipment. It briefly describes the research progress in the manufacturing of large-sized titanium alloy ingots and components, low-cost production techniques, and the preparation technology of seamless tubes for energy extraction equipment. The main existing problems at present are also proposed, with the expectation of providing references for research on the preparation technology of titanium alloy materials and their components for ships and energy equipment.更多还原
