The dynamic recrystallization of the Ni-based superalloy under the supergravity stress and high temperature
The occurrence of recrystallization will greatly decrease the service life of superalloy blades. The dynamic recrystallization of a Ni-based single crystal superalloy under supergravity stress and high temperature was studied. When tested at 950 °C, only one recrystallization layer is formed on the surface, whereas this changes to two recrystallization layers when tested at 1050 °C. The supergravity produces a stress gradient in the sample, and the nucleation and growth of the recrystallized grains increase with the stress at both temperatures. This work helps to recognize the recrystallization behavior of superalloy under service conditions.
