Abstract: The creep damage caused by the centrifugal stress is one of the main failure mechanisms of the blade, so it is very important to study the creep deformation behavior of the nickel-based single crystal superalloy. Based on the typical service conditions of the single crystal blade, this paper reviews the creep deformation mechanisms under the conditions of the high temperature-low stress and the medium temperature-high stress. It is suggested to study the creep behavior of the single crystal superalloys with typical defects and the effect of the oxidation and the hot corrosion on the creep-fatigue deformation damage mechanism.

Key words： nickel-based single crystal superalloy creep deformation behavior damage mechanism
