Abstract
A metallic component is by at least one peripheral edge. The component includes at least one elongated treated zone having a length substantially greater than its width. This treated zone is spaced away from and disposed generally parallel to the peripheral edge of the component and the entire thickness of the component within the treated zone is in a state of residual compressive stress. Crack growth from the edge due to fatigue or damage is resisted.
