In-situ study the low-cycle fatigue deformation behavior of a fourth-generation nickel-based single crystal superalloy at 1100 °C

In-situ study the low-cycle fatigue deformation behavior of a fourth-generation nickel-based single crystal superalloy at 1100 °C

An in-situ fatigue testing device, equipped in scanning electron microscope (SEM) and designed for long-time high temperature and complex stress testing conditions, was developed. The fatigue crack initiation and propagation behavior of notched Nickel-based single crystal superalloy (Ni-SX) was stud...
