Abstract
In this paper, the recrystallization evolution of single crystal superalloy M4761 at different solid solution temperatures after different sandblasting stress and different blasting time is studied. The results show that the sample is treated by solution treatment after blasting. When the solution temperature reaches the γ' phase dissolution temperature, the depth of the recrystallized layer increases rapidly, and the γ' phase dissolution temperature is not reached. The depth of the recrystallized layer grows slowly or Recrystallization does not occur; the depth of the recrystallized layer increases with the blasting time; but as time increases, the growth rate gradually becomes slower overall; the solid solution effect of the single crystal superalloy M4761 is best around 1180°C, a fine γ' phase is obtained and the structure is uniform; the grain boundary is composed of a coarse γ' phase, and the recrystallized region gradually increases in size from the edge of the sample to the grain boundary.
