摘要：

Fatigue cracking is one of the most common damage modes of aeroengine hot-end components, usually subjected to mixed-mode cracking. In this study, mixed-mode fatigue crack growth experiments at 550 ? are carried out using compact tension shear specimens made of nickel-based superalloy GH4169. Adaptive finite element method was used to verify several models at high temperature. The accuracy of angle dependent models was higher at 550 C, and the rate of da/dN increased and decreased twice with crack propagating, which is different from room temperature (20-25 C). This research could provide a basis for lifespan prediction of aeroengine hot -end components.
