dc.description.abstractA significant reduction in the fatigue life of cross-weld P91 specimens was observed in tests at 538 and 566 °C compared to that at 25 °C. The remarkable reduction of the fatigue strength was directly correlated to the shift of the fatigue cracking locations from the BM region at 25 °C to the interface between the intercritical heat-affected zone (ICHAZ) and BM at elevated temperatures. The low-cycle fatigue (LCF) resistance deterioration mechanisms were attributed to synergic interactions between a high rate of microstructure deterioration accompanied by severe plastic deformation and lower strain hardenability in the ICHAZ region at elevated temperature. © 2022 Elsevier Ltd-
