DüsseldorfNovel alloys for automotive lightweight design and airplane turbines, materials for sustainable energy conversion and storage, and the development of big data and machine learning methods – these are just a few examples of the research areas that are being investigated by the scientists of the Max-Planck-Institut für Eisenforschung. The team of engineers, material scientists, physicists, and chemists develops tailored materials and methods for mobility, energy, infrastructure, and information. To this end, the researchers study complex materials with atomic precision under real environmental conditions.

Department of Structure and Nano- / Micromechanics of Materials
Plasticity, fatigue, and fracture of materials are usually initiated by local deformation processes.
The mission of the Department Structure and Nano-/Micromechanics is to develop experimental methods to perform quantitative nano-/micromechanical and tribological tests for complex and miniaturized materials,
to unravel the underlying deformation mechanisms by advanced microstructure characterization techniques from the micrometer level down to atomic dimensions, to establish material laws for local and
global mechanical behavior, and finally to generate nanostructured materials and high temperature intermetallic materials with superior mechanical properties. The in-depth microstructure investigations
include atomic resolved high-resolution (scanning) transmission electron microscopy (STEM/TEM), analytical and conventional TEM, scanning electron microscopy with electron backscattered diffraction (SEM/EBSD),
focused ion beam microscopy (FIB), X-ray diffraction and synchrotron radiation techniques. A cornerstone will be the combination of advanced characterization and mechanical testing in form of in situ nano-/micromechanical experiments which will permit to simultaneously observe the microstructural changes while measuring the mechanical response. The gained insights will be used to quantitatively describe and predict the local and global material behavior and to design superior nanostructured materials and high temperature intermetallic materials by using local confinement effects.
The synthesis of miniaturized nanostructured materials will be done by thin film deposition techniques.

It has long been understood that hydrogen has a negative effect on metals like iron and steel. Studying this phenomenon is not easy because of the fact that hydrogen is everywhere, is extremely small and is in constant motion. In this video, MARÍA JAZMIN DUARTE CORREA explains how new technologies can help to pin down the impact of hydrogen in this context. Focusing on the particular challenges involved in studying diffusible hydrogen, Duarte explains how nano indentation can be used to specifically identify its effects. Looking forward, the research seeks to support the development of materials that are resistant to deformation caused by hydrogen. This has particular relevance for the energy sector where the storage and transportation of hydrogen presents a pressing challenge.
