Abstract High cycle fatigue (HCF) behavior of the second generation single crystal nickel–based superalloy DD98M without Re addition at 900 ℃ was investigated. The results indicate that HCF lifetime is reduced with increase of cyclic stress amplitude. Compared to smooth specimens, the fatigue lifetime and strength of notched specimens are decreased markedly. The fatigue strengths for smooth and notched specimens are 574 MPa and 360 MPa, respectively. Fracture observation by SEM shows that there exist many sites of crack initiation for notched specimens due to stress concentration of the notch, while for smooth specimens, crack generally initiates at pores and inclusions on the surface or subsurface. Deformed microstructures observed by TEM reveal that for smooth specimens, dislocation movement in the matrix is the main deformation mechanism and shearing γ' particles by dislocation pairs occurs occasionally under high stress level. In contrast, cutting γ' phases by partial dislocations, which formed stacking faults in γ', is the dominant deformation mechanism for notched HCF specimens.

Key words: single crystal superalloy high cycle fatigue deformation fracture microstructure
