Abstract Scope |
This paper focusses on the monitoring of production processes and material evolution under fatigue loading by non-destructive measurement methods, e.g. micromagnetic Barkhausen noise and eddy current. These very versatile and flexible techniques offer time-efficient possibility for the inspection of surface integrity of components. Approaches for a robust in-situ evaluation of surface integrity induced by manufacture, as well as the development of models for fatigue damage evolution, especially for materials with regard to high-performance and long-term sustainability, are presented. Different mechanisms are considered, e.g. production-induced formation of white etching layers (WEL), fatigue-induced relaxation of residual stresses and microstructural damage of component edge zone under fatigue loading. The mechanism-based consideration of influencing variables and cause-effect relationships is of decisive importance, since the effect interference represents a central challenge in identification of robust correlations for industrial applications. |
