| 英文摘要 | By using quasi-in-situ EBSD, we successfully probed the nucleation and growth of recrystallized grains during sub-solvus annealing at 1300 degree celsius of an as-cast single-crystal superalloy after pre-compression. It clearly indicated that recrystallization nucleated in the interdendritic region through low-angle grain boundary migration under the experimental condition rather than subgrain coalescence or thermal twinning. Despite being hindered by the undissolved gamma ' precipitates in the interdendritic region, these newly formed high-angle grain boundaries could still migrate rapidly. However, the migration velocity will slow quickly as the stored energy decreases. During 10.0-min annealing, the grain boundaries could migrate 14.4-27.4 mu m, but the recrystallized grains were still confined in the interdendritic region without abnormal growth. These results provide novel perspective on the comprehension of recrystallization nucleation in single-crystal superalloys and the migration of newly formed high-angle grain boundaries under the hinderance of gamma ' precipitates, and are valuable for developing process to control recrystallization. |
