钛合金的正式开发和应用仅仅是最近 50年来才开始的 ,并且在 50年代几乎只有美国一国在进行研究 ,最早开发成功了Ｔｉ 6Ａｌ 4Ｖ ,该合金直到目前其使用量已占全部钛合金的 75%～ 85%。高强度钛合金几乎都是利用α相和 β相双相强化的合金 ;唯有Ｔｉ Ｃｕ系合金是通过合金元素
The official development and application of titanium alloy only started in the last 50 years, and almost only the United States in the 1950s was conducting research and the first successful development of Ti 6Al 4V, the alloy up to now its use has accounted for all the titanium alloy 75% ~ 85%. Almost all high-strength titanium alloy is the use of double-phase α-phase and β-phase strengthening of the alloy; the only Ti Cu-based alloys are alloying elements
