... in the length of the tearing ridge in the fracture morphology. In addition, the fatigue life considerably increased, initially increasing and then decreasing as the number of rolling passes increased. After four cycles of USRP, the fatigue life of the samples was the highest, which was about 18.4 times...

.... Three samples were tested under each condition, and the average values were reported. Additionally, fractography analysis was performed using a scanning electron microscope (SEM) to examine the fracture surfaces of the tested samples. The SEM analysis provided insights into the failure mechanisms...
