摘要
钛合金具有密度小、强度高、耐高温和抗腐蚀性好等优点,在航空航天、船舶、汽车、医疗、化工和能源等领域获得了广泛的应用。首先从航空航天和非航空航天领域综述了钛合金的应用现状;然后从热处理、焊接性能和表面处理技术三个方面综述了钛合金加工工艺及性能;最后叙述了钛合金的最新成形技术,即超塑性成形技术、近净成形技术、激光成形制造技术及计算机模拟技术,并展望了钛合金的应用前景及发展方向。
Titanium alloy is widely used in aerospace, shipbuilding,automotive, medical, chemical and energy industries due to its low density, high strength, high thermostability and corrosion resistance. First,the application of titanium alloy are reviewed from the aerospace and non-aerospace aspect. Then the processing technology and perfor- mance of titanium alloy are summarized from heat treatment, welding performance and surface treatment. Finally the latcsl forming technology, such as superplastic forming, net-shape forming technology, laser forming manufacturing technology and computer simulation techniques are described. The application prospects and development direction of titanium alloy are dicussed.
