摘要
过去的30年里,Ti2AlNb基合金获得了广泛关注。作为替代镍基高温合金的选择之一,其优异的综合力学性能适应了未来航空发动机对高比强度、高比刚度的轻质高温结构材料的迫切要求,对于降低飞行器的自重,提高发动机结构效率和高温服役性能具有重要意义。
During the past 30 years, enormous research has been devoted to the development of Ti2A1Nb- based alloys for applications in gas turbine engines. Ti2A1- Nb, as a light alloy for replacing Ni-based superalloys, ex- hibits a good combination of specific strength and stiffness. The application of this alloy will have a profound influence on improving structural efficiency of future advanced aero- engines.
