摘要：
The effects of the solution and aging treatment on the microstructure, the tensile properties at room-temperature and 650 ℃ and the stress rupture of GH4169 superalloy were investigated. The results show that after solution at 980 ℃ and aging at 720 ℃ plus 620 ℃, both the yield strength and ultimate strength of the superalloy at room-temperature and 650 ℃ are highest; after solution at 960 ℃ and aging at 720 ℃ plus 620 ℃, the stress rupture life of the superalloy tested at 650 ℃ and 725 MPa is the longest; the solution treatment can adjust the amount of δ phase, primary strengthening γ phase precipitates upon aging at 720 ℃, while assistant strengthening γ' phase precipitates at 620 ℃.
