A Study of the Creep-Fatigue Damage Mechanism of a P92 Welded Joint Using Nanoindentation Characterization

A Study of the Creep-Fatigue Damage Mechanism of a P92 Welded Joint Using Nanoindentation Characterization

In fossil fuel and nuclear power plants, welded joints continuously experience creep-fatigue loading, which can result in premature cracking during the in-service term. To study the creep-fatigue interactive (CFI) behavior, the CFI test of P92 steel was performed with different strain rates at 823 K...
