Formation mechanism of serrated grain boundary caused by different morphologies of γ′ precipitates in GH4742 superalloy

This study investigates the evolution mechanism of the fan-type γ′ structure and its effect on serrated grain boundary in GH4742 superalloy under different cooling rates. The formation mechanism of the fan-type γ′ structure and the mechanism of serrated grain boundary in GH4742 superalloy are discus...
