摘要
钛合金紧固件因其密度小、高比强、耐腐蚀等性能广泛应用于航空航天领域。着重对航空紧固件用钛合金材料的发展现状进行综述。结合紧固件用钛合金的发展,介绍了国内外紧固件用钛合金的应用现状,并对比分析了紧固件用钛合金材料的性能特点。同时,结合先进飞机对高性能紧固件的需求,介绍了几种紧固件用高强韧钛合金材料及其紧固件加工工艺。
Titanium alloy has been widely used for aerospace fasteners industry due to its low density, high yieldstrength, and good corrosion resistance. The research and prospect of titanium fasteners are reviewed. Nationally and internationally,the recent development and application of titanium fasteners are introduced. The tensile properties of some candidatealloys for high-strength fastener application are summarized and compared. Some high-strength β-titanium and thetechnical processes of bar or wire for fasteners are introduced on the basis of requirement for advanced aircraft.
