- •
Fatigue failure in 17-4PH originates preferably from non-metallic inclusions.
- •
The fatigue strength can be estimated using the
parameter model.- •
The stress ratio dependency is determined by fractographic investigations.
- •
The lower bound of the fatigue limit is predicted using the extreme value theory.
- •
The role of optically dark areas in fish-eye fractures is discussed.
