Abstract

Deformation mechanisms of an Ni-based superalloy during low-cycle fatigue at various temperatures were studied. A new configuration of cross-slip dislocation was observed in the γ matrix during the deformation at 760 and 900 °C, which is an important component of the slip band at 900 °C. Slip bands with different morphologies were observed at room temperature and 900 °C, corresponding to the obvious work-hardening. It was observed that stacking faults spread throughout the γ/γ′ interface.
