文摘

Fatigue and induction heating thermo-mechanical fatigue (TMF) were performed on Hastelloy X superalloy. A model based on damage contributions due to pure fatigue and cyclic creep has been presented for predicting TMF crack growth rates. The TMF crack healing or crack closure occur during application of induced eddy currents were investigated explicitly.
