一种超塑性钛合金板材及其制备方法
摘要：
本发明涉及一种超塑性钛合金，该合金的组成及各元素含量的重量百分比(wt％)为：Al：2～4、V：2～4、Fe：0.2～2、Mo：0.2～3、Cr：0.2～3、Nb：0.2～3、O：0.1～0.3、Ni：0～4.5、Co：0～5，余量为Ti。本发明还公开了一种采用该超塑性钛合金制备板材的方法。本发明的钛合金及钛合金板材具有优异室温和高温力学性能匹配，满足超塑成形时对钛合金的要求。
摘要（英）：

The invention relates to a superplastic titanium alloy. The superplastic titanium alloy is prepared from the following elements in percentage by weight: 2-4wt% of Al, 2-4wt% of V, 0.2-2wt% of Fe, 0.2-3wt% of Mo, 0.2-3wt% of Cr, 0.2-3wt% of Nb, 0.1-0.3wt% of O, 0-4.5wt% of Ni, 0-5wt% of Co and the balance of Ti. The invention also discloses a method of preparing the panel by adopting the superplastic titanium alloy. The titanium alloy and the titanium alloy panel provided by the invention are excellently matched in room temperature and high-temperature mechanical properties, and meet the demandon the titanium alloy during superplastic forming.
