B4: 3D-deformation behavior of nanoporous metals and nanocomposites

3D-deformation behavior of nanoporous metals and nanocomposites

Project B4 will be realigned during the second funding phase to introduce the possibilities of the high-resolution X-ray microscope and to use it for a cross-scale investigation of mechanical size effects. The project focuses on the new X-ray microscope Zeiss Xradia Ultra 810, which complements the already established tomography techniques in CENEM (360 ° ET, 3D-FIB, APT) across scales. The device currently has the highest spatial resolution of a laboratory device (<50 nm) and is equipped with a micromechanical in situ loading unit. This allows correlated mechanical and structural 3D analyzes, which are established in cooperation with Project Z. D The 3D data obtained from X-ray tomography are used to elucidate the deformation behavior for cross-scale correlative simulations (FEM / MD). In addition to the tomographic examinations, further methods of electron microscopy and X-ray scattering are used to elucidate the structure.
