The main damage which affects fatigue life is initiation and growth of cracks.
- class="label">•
The fatigue life was extended by removing small cracks.
- class="label">•
There is a critical length of fatigue crack which causes the loss of ductility.
- class="label">•
The loss of fracture ductility is related to the fracture types in tensile tests.
