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, thermall...
