Sažetak
High temperature creep, isothermal cyclic creep and creep with additional thermomechanical fatigue stress component were performed on a wrought nickel base superalloy. The effect of the individual tensile hold periods as well as combined effect of hold periods and the thermo- mechanical fatigue stress effect was studied. The deformation behaviour was compared with of static creep. The experimental results show that the introduction of tensile hold periods only to monotonic creep causes an increase in the facture life proportional to the duration of the individual hold periods. As additional thermo-mechanical fatigue stress component produced by cooling at cyclic creep between the individual cycles resulted in more strain reduction and more pronounced strengthening.
