随着超音速飞机的发展,国内外都开展了对钛合金铆钉丝的研究。最早研究的是α和α+β型钛合金,但没得到满意的结果。后来由于β型钛合金的发展,高强钛合金冷镦铆钉才有可能成为现实。据报道,制造钛合金冷镦铆钉的较好材料是美国研制的过时效状态下使用的β_Ⅲ合金。这种材料在固溶状态下能冷镦成铆钉,过时效处理后可用压铆机和铆枪进行冷铆,并具有良好的热稳定性和
With the development of supersonic aircraft, both at home and abroad have carried out research on titanium alloy rivets. The earliest studies were α and α + β titanium alloys, but did not get satisfactory results. Later, due to the development of β-type titanium alloy, high-strength titanium alloy upsetting rivets may become a reality. It is reported that the manufacture of titanium alloy cold heading rivets better material developed by the United States used in the aging state β_ Ⅲ alloy. This material can be cold heading into rivets in solid solution state, can be riveted by riveting machine and riveting gun after over-aging treatment, and has good thermal stability and
