Abstract:
In this paper, the research progress of the surface-recrystallization control technology of Ni-based single-crystal superalloy is reviewed and analyzed from several aspects including the mechanism and surface effects of surface recrystallization, the component design for recrystallization prevention, and recrystallization control technology during thermal forming or cold working progress. The focus is on discussing recrystallization control technology in different countries. Meanwhile, the gap between China and some other countries in this respect is pointed out, and the future research scope is also discussed.
