“…Over the past 50 years, numerous theoretical analyses, experimental explorations, and computer simulation studies have been conducted on crack deformation of superalloys. Most studies have investigated thermomechanical fatigue (TMF) of nickel‐based superalloys, but the majority of the work have been aimed at characterizing the cyclic deformation behavior and crack initiation life . For instance, crack paths in single‐crystal Ni‐based superalloys under isothermal and TMF show that crack paths under isothermal and TMF are influenced by several factors, including temperature, strain range, dwells during the cycle, microstructure, crystal orientation, the environment, the strain‐temperature phasing in TMF, and frequency .…”
