Prediction of Fatigue Life of Welded Joints Made of Fine-Grained Martensite-Bainitic S960QL Steel and Determination of Crack Origins

<div>The pictures of fatigue fractures have been observed during fractographic investigation. Samples made of S960QL steel tested under total strain amplitude: (a) <i>ε</i><sub>a</sub> = 0.3% and (b) <i>ε</i><sub>a</sub> = 1.5%.</div>
