摘要
以Ｔｉ－４８Ａｌ－２Ｃｒ－２Ｎｂ为先导的γ钛铝化合物合金很有可能用于未来的高性能先进航空喷气发动机。与常规钛基及镍基合金相比，这种合金的工作温度可达到８００℃并且有难燃性。本文重点介绍其设计性能、铸造及焊接特性，也介绍了成本问题。
The cast gamma TiAl alloys, with the Ti48Al2Cr2Nb leading the way, have a good potential in the future high performance jet engines. Compared to conventional titanium and nickel alloys, they have a temperature capability of 800℃ without coatings and excellent resistance to ignition. In this article description is focused on design properties, casting and welding characteristics. Cost problem is touched also.
