Magnets are the key elements in many of today's technologies for energy conversion. This Collaborative Research Centre (CRC) addresses strong permanent magnets with a maximized hysteresis as well as soft magnets with a minimized hysteresis.
This CRC/TRR aims at developing affordable, environmentally friendly and efficient magnetic materials for future energy conversion technologies.
Application areas are future mobility and sustainable electricity generation (i.e. wind turbines, electric cars etc.) on the one hand. For this purpose, strong permanent magnets are required.
One the other hand, soft magnets are needed for magnetocaloric cooling.
Both application areas require affordable, environmentally friendly and efficient state-of-the art functional materials.
What is the relation between micro-/nanostructure and the desired (“good”) magnetic properties?
Which processing techniques lead to the desired microstructure and therefore to the desired magnetic properties?
Can we substitute the precious rare earth elements or reduce their content and maintain or even improve the magnetic properties at the same time?
How do we need to proceed in order to obtain powders suitable for additive manufacturing?
A detailed understanding of what is happening within the material on all length scales will enable the researchers of the CRC to adjust the local and global properties of a magnetic material by additive manufacturing and severe plastic deformation methods. Together with their colleagues from Max-Planck-Institut für Eisenforschung (MPIE) and Ernst Ruska-Centre for Microscopy and Spectroscopy with Electrons at Jülich Research Centre, the scientists of TU Darmstadt and Universität Duisburg-Essen will develop new processing methods for innovative magnet materials. Material scientists, physicists, chemists and process engineers will work on magnetic materials by manipulating individual atoms but also by deforming massive samples. By linking the experimental and theoretical groups together in one centre they will be able to continuously cross-link their developments. Artificial intelligence, which accelerates materials discovery and the rapid identification of the most promising material combinations, will also be employed in HoMMage.
