西北有色院创新研制的船用钛合金

钛及钛合金以其优异的综合性能已成为一种理想的船用金属材料。主要介绍了西北有色金属研究院设计研制的具有我国自主知识产权的Ti75，Ti-B19，Ti31和Ti91 4种不同强度级别的性能优异的船用钛合金。其中Ti75和Ti31已工业化生产，并得到成功应用，Ti-B19和Ti91也具有良好的应用前景。在此基础上，初步建立了我国船用钛合金的体系。

Titanium Alloys for Shipbuilding Developed by Northwest Institute for Nonferrous Metal Research

Because of low density, high specific strength, corrosion resistance to sea water and so on, titanium and its alloys are the ideal metal materials for shipbuilding. Four different alloys, i.e. Ti75, TiB19, Ti31 and Ti91,having good comprehensive properties with different strength scale, were designed and developed by Northwest Institute for Nonferrous Metal Research. Based on these four alloys, the national Ti alloy''s system of China has been set up.
