Functional Materials is part of new DFG-funded research training group (GRK) “LokoAssist” at TU Darmstadt

The German Research Foundation (DFG) has approved the new research training group “LokoAssist – Seamless Integration of Assistance Systems for Natural Human Locomotion” at TU Darmstadt and the University of Heidelberg. The collegium will be funded for four and a half years starting in 2022 with a budget of around 6 million euros.

A roadmap towards excellent cyclic stability combined with large elastocaloric and magnetocaloric effects

New publication: Ni-Mn-based metamagnetic shape-memory alloys are highly promising for solid-state caloric cooling applications but commonly exhibit structural and functional fatigue during cyclic operation.

Under the lead of the Functional Materials group of TU Darmstadt, an international consortium of experts in the field of magnetocalorics has developed a standardization document for the correct measurement of the most important properties for caloric materials.

The working group Magnetism of the German Physical Society (DPG) has awarded Benedikt Beckmann the Diploma / Master Prize 2021 at the Autumn Meeting of the Condensed Matter Section.

Three PhD students from the Functional Materials group participated in the „European School on Magnetism"in Cluj-Napoca, Romania.

New publication in Advanced Materials

Ultrastrong and ductile bulk high-entropy Fe-Co-Ni-Al-Ta alloy with excellent soft magnetic properties were obtained by introducing a high volume fraction of coherent and ordered nanoprecipitates into the alloy matrix. The high coherency between the homogeneously dispersed nanoprecipitates and the alloy matrix contributed significantly to increase the mechanical properties without affecting the magnetic domain wall motion, preserving soft magnetic behavior.

New publication in Acta Materialia

In this new publication, we reveal a crucial role of grain orientation on the stress-induced martensitic transformation as well as the impact of grain size on the mechanical stability and the magnetic-field-induced transformation dynamics.

Joint project of Material Science and Mechanical engineering targets powder production, qualification and processing evaluation of functional magnetic materials by Laser-Powder-Bed-Fusion

New publication shows: Pr-Fe-Cu-B alloy design and AM process control lead to high magnetic coercivity due to a novel and unconventional microstructure compared to sintered or hot deformed Nd-Fe-B magnets.

We congratulate our colleague Bahar Fayyazi to her successful PhD defense.

At the 26th International Workshop on Rare-Earth and Future Permanent Magnets and their Applications (REPM2021) Prof. Oliver Gutfleisch received the REPM achievement award “For his outstanding work on the research and development of permanent magnet materials” (June 10, 2021).
