Abstract Abstract In this paper, the recrystallization of the surface deformed structure of DZ4 directionally solidified superalloy was studied by SEM and X-ray diffraction. The results show that under the condition of two-hour holding, recrystallization takes place at 1000℃.The recrystallization layer increases slowly with the temperature rise when the heat treatment is performed at the temperature lower than that of the -solutioning, whose structure is cellular one, but increases rapidly when performed at the temperature higher than that of the -solutioning and the larger phase within the recrystallization layer decreases until totally disappeared. The recrystallization formed at temperature of 950℃ and 870℃ for long holding time is cellular structure. The rate and thickness of recrystallization mainly depend on temperature, which have little relation to holding time.

Key words: DZ4 alloy surface recrystallization
