The activation energy for dynamic recrystallization and stress exponent were calculated to be 551 kJ/mol and 7.73, respectively......
the superalloy is annealed at solution treatment temperature. The nucleation of recrystallization originates from the dendritic core, where rapid dissolution of γ’ particles occurs. Cellular recrystallization...Surface recrystallization of a single crystal nickel-base superalloyJie Meng1), Tao Jin1,2), Xiao-feng Sun1), and Zhuang-qi Hu1) 1) Department of Superalloys, Institutes of Metal Research, Chinese......
of process parameters (strain, strain rate and temperature) on the fraction of DRX and the average recrystallization grain (R-grain) size were investigated and discussed. It is found that larger stain... the temperature and the stain rate are kept constant during hot compression, the amount of recrystallization nuclei grows significantly with the increase of strain. The fraction of DRX as well as the average......
