| Abstract Scope |
This study presents innovative approaches for fatigue assessment of metals, with a particular focus on the critical role of surface integrity, for example in terms of residual stresses, hardness, and microstructure. Non-destructive testing (NDT) methods are employed to evaluate these subsurface characteristics effectively and monitor steels under fatigue loading conditions. For instance, magnetic Barkhausen noise (MBN) analysis is employed to assess the evolution of residual stresses and detect machining-induced white etching layers. Additionally, fatigue testing is conducted under corrosive environments to elucidate the combined effects of mechanical stress and corrosion on steel durability. Hydrogen embrittlement studies further reveal the susceptibility of steels to premature failure due to hydrogen charging. The integration of these techniques aims to provide a comprehensive understanding of the mechanisms governing the fatigue behavior of metals. Based on this, concepts for enhancing material performance in various industrial applications are presented. |
