Zusammenfassung: Metals are the most widely used engineering materials, and their reliability is crucial for their applications. Engineered metallic materials exhibit diverse mechanical properties, defects, phases, microstructures, and chemical compositions. These microstructural features govern the deformation and failure of metals. Recent advances in material characterization techniques have provided insights into deformation mechanisms across a wide range of length and time scales. At the microscale, electron microscopy is widely used to reveal local crystal orientations and microstructures. At larger scales, digital image correlation (DIC) techniques and X-ray diffraction have enabled the measurement of internal stresses and lattice strains during deformation. Emerging techniques, such as 3D tomography, atom probe tomography (APT), and a focused ion beam (FIB), allow for the three-dimensional reconstruction of microstructures. Numerical modelling techniques have also progressed significantly. The finite element method (FEM) remains a cornerstone of mechanical simulation. Incorporating crystal plasticity models into FEM enables the consideration of microstructural features at the grain level. At a lower scale, discrete dislocation dynamics (DDD) and molecular dynamics (MD) simulations capture the activities of dislocationsPPN: PPN: 1983954284Package identifier: Produktsigel: ZDB-94-OAB
