Description
Tie-line third-generation single-crystal Ni-base superalloys, named TMS75a, TMS-75, and TMS-75b, were cast with different γ' volume fractions. TMS-75 showed the best thermo-mechanical fatigue (TMF) behaviour, while TMS-75b showed the best creep behaviour. The different creep and TMF behaviours of the tie-line superalloys can be correlated with their differences in microstructure. The present work suggests that making a compromise between creep and TMF behaviours by changing the volume fraction of the γ' phase is important when designing new superalloys. (orig.)
