摘要：

The isothermal and thermo-mechanical fatigue behavior of the ferritic-austenitic duplex stainless steel X2CrNiMoN22-5-3 is investigated in the temperature range of 100-600 degrees C. Furthermore, isothermal and thermo-mechanical fatigue tests on single-phase ferritic and austenitic reference steels are carried out within the same temperature range. A recently developed fatigue-lifetime description is applied and modified for all tests as well as on the different steels individually, providing appropriate fatigue-life predictions.
