要旨
Advanced materials increasingly require integrated characterization and modeling strategies combining microstructural analysis with mechanical testing across multiple length scales. At the Chair of Materials Test Engineering (WPT), at the TU Dortmund University in Germany, these advanced methodologies for fundamental basic research and industrial technology transfer are continuously being further developed. The work covers additive manufacturing of metals and lattice structures, fatigue in the very-high-cycle (VHCF) regime, hydrogen-induced embrittlement of structural steels, and characterization of sustainable biomaterials. A wide variety of testing systems are combined with complementary techniques, including computed tomography (CT), digital image correlation (DIC), scanning electron microscopy (SEM), X-ray diffraction (XRD), and microhardness testing, to establish comprehensive process-structure-property relationships. Particular emphasis is placed on understanding how manufacturing-induced microstructures, defects, residual stresses, and environmental conditions influence deformation and damage evolution. Furthermore, this contribution illustrates the importance of close cooperation between academia and industry in advancing innovative testing solutions and accelerating the transfer of scientific findings into engineering applications.
