美国空军材料研究所已对钛铝金属间化合物 Ti_3Al 和 TiAl 进行了十余年的探讨,到目前为止已制成涡轮部件在 F100发动机上试车,取得了初步满意的结果。一些关键性工艺已在试验工厂条件下进行了评定,如铸锭浇铸、铸造、锻造、轧板、精铸、超塑性成形、扩散连接、等温锻和机加工 The US Air Force Institute of Materials has been titanium and aluminum intermetallics Ti_3Al and TiAl for more than ten years of discussion, so far has been made of turbine components on the F100 engine test, and achieved initial satisfactory results. Some of the key processes have been evaluated in pilot plant conditions such as ingot casting, foundry, forging, plate rolling, investment casting, superplastic forming, diffusion bonding, isothermal forging and machining
