摘要

This study presents non-destructive testing techniques for the fast assessment and detailed characterization of turbine blades. Different inspection techniques were developed to realize a flexible and adaptive inspection sequence. In addition to an initial inspection, the advantages of this inspection system with regard to quality assurance measures are also discussed. In this context, the focus is on regeneration. Furthermore, fatigue tests with combined non-destructive testing techniques are presented and the benefit of this new approach for in-situ monitoring of the microstructural evolution is shown.
