Claim 17:
18. A method for producing an engine component, wherein
at least one first loading zone is formed on the engine component for dynamic loads arising at the engine component when the engine component is built into an engine and when the engine is operating, and
a second loading zone is provided spaced at a distance from the first loading zone on the engine component and configured for dynamic loads arising at the engine component when the engine component is built into an engine and when the engine is operating,
wherein at least one spatially delimited modification zone with introduced internal tensile stress is formed on the engine component, wherein via the at least one spatially delimited modification zone, a crack propagating in the engine component is at least one chosen from guided to the second loading zone and guided within the second loading zone in order to avoid crack propagation in the first loading zone; and
wherein the at least one spatially delimited modification zone is provided in the second loading zone.
