| Abstract Scope |
High-performance structures based on high-strength steels and light metal alloys offer huge potential for increasing capability and efficiency for automotive and aerospace industries. Advanced characterization techniques – based on coupled testing strategies and measurement methods – are investigated to pave the way for development acceleration and market acceptance, especially for innovative material systems with regard to high-performance and long-term sustainability under service loading. For high-strength steels, a monitoring and control of the production process by micro-magnetic evaluation offers the possibility to detect the development of various local material properties during drilling, milling, and forming processes. For light metal alloys processed by conventional or additive manufacturing, a damage tolerant design for fatigue applications can be ensured by defect detection techniques like computed tomography. The defect distribution can be combined with simulation approaches in order to estimate the effect of defects on the fatigue behavior and damage tolerance. |
