Spin+Mechanical Sensing: Investigation and characterization of strain induced spin phenomena in engineering materials (B08)

该项目有助于可靠地确定金属材料（特别是钢）的微观结构变化与磁性能之间的相关性，这些变化是通过先进的磁性（即基于自旋的）表征方法由单调（拉伸试验）或循环（疲劳）机械载荷引起的。我们应用磁光克尔效应（MOKE）显微镜和微磁，多参数，微结构和应力分析（3MA）传感器技术的循环加载的工程材料，并与其目的是应用非破坏性的，基于自旋的方法来识别早期疲劳状态的工程材料。因此，该项目将Spin+X的工作扩展到机械工程的基本方面。

The project contributes to a reliable determination of the correlations between microstructural changes and magnetic properties in metallic materials, especially steels, induced by monotonic (tensile test) or cyclic (fatigue) mechanical loading by means of advanced magnetic, i.e. spin based, characterization methods. We apply magneto-optical Kerr effect (MOKE) microscopy and Micromagnetic, Multiparameter, Microstructure and stress Analysis (3MA) sensor technology on cyclically loaded engineering materials, and therewith aim to apply non-destructive, spin based approaches for identification of early fatigue states in engineering materials. Thus, the project extends the work in Spin+X to essential aspects of mechanical engineering.
