Abstract
The high temperature low cycle fatigue tests of 1Cr11Ni2W2MoV are conducted under total axial straincontrol. The specimens are tested under fully reversed strain. The relationships of cyclic strain-life, stress-strain and stress-life are analyzed. Manson-Coffin method and a new method based on power transformation theory are evaluated by the low cycle fatigue data. The results showed that two methods can effective predict low cycle fatigue life of 1Cr11Ni2W2MoV at 360 °C. Prediction accuracy within ± 1.65 times scatter band. The life prediction capability of new methods proves more effective and accurate than Manson-Coffin method. The new method has smaller standard deviation than Manson-Coffin method. Manson-Coffin method and new method have standard deviations of 0.32 and 0.18 respectively.
