Study on High-Temperature Fatigue Properties and Notch Sensitivity of Haynes 230 Alloy TIG-Welded Joints
This study investigates the high-temperature high-cycle-fatigue behavior of TIG-welded Haynes 230 alloy using smooth and notched specimens (Kt = 3) at 850–950 °C. Both elevated temperature and notch effect significantly degrade fatigue performance. As temperature increases, thermally activated crack initiation and prop...
