摘要
对于钛合金来说,合金元素的种类以及含量对合金性能有很大的影响.而对于β钛合金,主要问题是如何选择β稳定元素以及控制β稳定元素的添加量.综述了不同合金元素对β钛合金的影响,并总结了国内外高强β钛合金的发展过程及现状.重点介绍了美国的Ti-1023、β21-S和俄罗斯的BT22、Ti-5553以及中国的Ti-5523合金.此外,从添加小尺寸间隙元素来控制合金相的大小、形态及种类的角度,对提升β钛合金强度进行了展望,以期使β钛合金的强度进一步提高.最后总结了 β钛合金发展过程中遇到的困难及β钛合金可能的发展方向.
Abstract
For titanium alloys,the type and content of alloying elements have a great impact on the properties of the alloy.For β-titanium alloy,the main problem is how to select β-stable elements and control the addition of β-stable elements.In this paper,the influence of different alloyed elements on β-titanium alloy is reviewed,and the development process and current situation of high-strength β-titani-um alloy at home and abroad are summarized.The American Ti-1023,β21-S,Russian BT22,Ti-5553 and Chinese Ti-5523 are mainly introduced.In addition,from the perspective of controlling the size,shape and type of the alloy phase by adding small size gap elements,the improvement of the strength of β-titanium alloy is prospected,in order to further improve the strength of β-titanium alloy.Finally,the difficulties encountered in the development of β-titanium alloy and the possible development direction of β-titanium alloy are summarized.
