到目前为止，已经有千余种钛铝合金涡轮增压汽轮机和排气活门在实际使用之中

到目前为止，已经有千余种钛铝合金涡轮增压汽轮机和排气活门在实际使用之中[4-5]。在由通用电气公司生产波音787飞机中，γ-TiAl合金已用于燃气涡轮发动机上[6]。钛铝合金在低压涡轮发动机叶片上的应用也在逐步实现中。
TiAl合金尽管有许多优良性能，但是该合金在某些方面依然存在不足，如室温下呈脆性, 缺乏足够的延展性, 变形加工性、耐磨性能较差, 高温(≥800 ̊C) 抗氧化能力低。如何改善TiAl合金的性质，是其可以成功应用于工业生产前必须考虑和解决的中心课题。

結果 (英文) 1:

To date, there have been thousands of titanium alloy Turbo turbine and exhaust valve in the actual use of [4-5]. Manufactured by the General Electric company in Boeing 787 aircraft, γ--TiAl alloys have been used in a gas turbine engine [6]. Application of titanium alloy in low pressure turbine blades is gradually achieved. Although there are many excellent properties of TiAl alloys, but remains insufficient in some aspects of the alloy, as is brittle at room temperature, lack of sufficient ductility, deformation, abrasion resistance ability is poor, and high temperatures (≥ 800 ̊ c) antioxidant capacity is low. How to improve the properties of TiAl alloys, is that it can be successfully applied to industrial production must be considered and addressed before the central topic.

結果 (英文) 3:

So far, there have been more than 1000 kinds of titanium aluminum alloy turbine turbine and the exhaust valve in the actual use of [4-5]. In the production of the Boeing 787 aircraft from the Ge Corp, gamma -TiAl alloys have been used in gas turbine engine [6]. Application of titanium aluminum alloy in low pressure turbine engine blade is in gradually implementation.
despite the many excellent properties of TiAl alloy, but the alloy in some respects still exist deficiencies, such as room temperature brittle, lack of sufficient ductility, deformation processing, wear resistance is poor, high temperature (C = 800) antioxidant capacity low. How to improve the properties of TiAl alloy,Is it can be successfully applied to consider and solve the central issue in industrial production must be.
