The plastic strengthening effect after long-term endurance and fatigue verification of aero-engine turbine blade single crystal superalloy
The elastoplastic behaviors of a nickel-based single crystal superalloy at 760 °C, 927 °C and 1100 °C were studied, respectively, after 815 °C/250 MPa lasting for 2000 h, 927 °C/205 MPa lasting for 2000 h and ...

Effects of Re on microstructure evolution of nickel-based single crystal superalloys
The high temperature creep and long-term aging tests of the second-generation (DD6) and the third-generation (DD9) single crystal superalloys with different Re contents were carried out. The effects of Re, dis...

Influence of microstructure degradation induced by pretreatment on the creep behavior in Ni-based single-crystal superalloy with different orientations
The effects of stress-free and stress-assisted pretreatments at a relatively high temperature on the creep properties of [001] and [011] oriented Ni-based single-crystal superalloys are investigated in this ar...

Effects of Blade Curvature on Fatigue Life of Nickel-Based Single Crystal Structures with Film-Cooling Holes
The curved thin-walled structures of multi film-cooling holes with different curvatures were adopted to simulate film-cooling turbine blades. The low cycle fatigue (LCF) characteristic was studied based on the...
