WebFretting fatigue experiments were performed on Inconel 690 specimens at room temperature and at the nuclear power plant operating temperature of 320 °C. By comparing the fretting fatigue test data at room temperature and 320 °C, this study analyzed the change in characteristics related to the fatigue limit at 107 cycles. WebJun 25, 2024 · Figure "Fretting processes in contact zone" ( Ref. 6.1-5 ): A major cause of fretting-inducing micro-movements is varying stiffness in contact surfaces. This causes uneven elastic deformations in the contact surfaces when subjected to dynamic loads, resulting in corresponding micro-movements.
