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.
