Abstract
- The effect of hold time with 0, 20, and 40 s on in-phase thermomechanical fatigue (TMF) behavior and life of P92 steel is investigated in this study. TMF tests are carried out under mechanical strain control with strain amplitudes of 0.40.4, 0.60.6, and 0.8%0.8\text{\%}, and temperature range of 550–650°C which is closely relevant to the operating condition in power plant. TMF tests are performed in a mechanical strain ratio of R=−1R=-1 and cycle time of 120 s. The fatigue life variation follows the sequence of Nf0s
