Through the coordinate and surface measuring technology, equipped with optical and tactile methods, the geometry of tools and prefabricated parts made of a wide variety of materials, as well as their contours and surface properties such as surface roughness can be recorded with great precision. The comprehensively equipped matrialography enables a detailed analysis of the microstructure and grain size, as well as hardness tests locally resolved, both on the surface and in-depth. The scanning electron microscopy instrument equipped with an extensive detector system (SE, BSE, EDX, and EBSD), allows detailed imaging of the sample surfaces down to a few micrometers (µm). Consequently, the microstructure and chemical composition can be precisely analyzed. In addition, residual stresses can be recorded using drill hole methods or non-destructively using X-rays (sin² psi method, scattering vector method, angle and energy dispersive X-ray diffraction) spatially resolved near-surface as well as in depth of the material. Subsequently, these residual stresses can be correlated with material properties such as service life.
On November 1st, 2023, the analytic team welcomed Dr. Hilke Petersen as the newest member. The chemist earned her doctorate in the field of chemical crystallography at the University of Bremen with a focus on establishing structure-property relationships before studying the atomic structure of novel catalysts, their structure-performance relationship, and their microstructure during the catalytic processes at the Max Planck Institute für Kohlenforschung.
In September 2024, the head of the analytics department apl. Prof. Dr. habil. Bernd Breidenstein will leave the IFW after 23 years for reasons of age and hand the management of the department over to Dr. Hilke Petersen. “Dr. Hilke Petersen has extensive knowledge of a wide range of spectroscopic and X-ray analytical methods, e.g. Raman/infrared spectroscopy and X-ray diffractometry, and will definitely enrich the department,” says apl. Prof. Dr. Bernd Breidenstein.
