On Creep Fatigue Interaction of Components at Elevated Temperature [PDF]
Journal of Pressure Vessel Technology, 2016 The accurate assessment of creep–fatigue interaction is an important issue for industrial components operating with large cyclic thermal and mechanical loads. An extensive review of different aspects of creep fatigue interaction is proposed in this paper. The introduction of a high temperature creep dwell within the loading cycle has relevant impact on

Creep-fatigue interaction in heat resistant austenitic alloys [PDF]
MATEC Web of Conferences, 2018 This work includes an investigation of two commercial austenitic steels: UNS S21500 (Esshete 1250) and UNS S31035 (Sandvik SanicroTM 25). The materials were exposed to isothermal strain controlled fatigue with load controlled dwell time at maximum strain.

Creep–Fatigue Life Estimation of Gr.91 Steel and Its Welded Joints
Metals, 2023 A series of creep–fatigue tests of Gr.91 steel were performed at 600 °C. Fatigue life was reduced by tensile strain holding. The minimum life reduction factor was approximately 0.3.

Impact of creep-fatigue interaction on divertor tungsten under high heat flux
Nuclear Materials and Energy, 2023 High heat flux as 20 MW m−2 during stationary operation can be foreseen in future fusion devices, leading to recrystallization and thermal creep in tungsten targets. Both recrystallization and thermal creep impact would play significant roles in service.
