摘要
GH903合金系沉淀强化型Ni-Fe-Co基低膨胀高温合金。本文研究了GH903合金650℃,200—2000h时效后的组织和室温及高温的力学性能。结果表明,在650℃该合金组织和性能是比较稳定的,能满足航空发动机长期使用的需要。
The microstructure and mechanical properties of a Ni--Fe--Co base su-
peralloy with low thermal expansion coefficient after aging at 650℃ for 200, 500,
1000 and 2000h have been investigated. It was found that they are stable at
650℃. This alloy is believed to fill the requirements for long time service to aircraft
engine.
