| Abstract | ||
| Fatigue tests were done to determine the S-N curves for Cu 65400 alloy specimens .The effect of laser shotting on the fatigue properties were investigated with stress ratio R=-1 at room temperature. Laser shotting of this alloy increases the life, endurance limits and compressive residual stresses. The largest increase in compressive residual stresses were observed at stress level 350 MPa. | ||
