Advanced methods for the development of high performance hard and soft magnetic materials — •Dagmar Goll and Gerhard Schneider — Aalen University, Materials Research Institute, Beethovenstr. 1, 73430 Aalen, Germany

Higher efficiency in electro mobility requires high performance and economic motor concepts. Recent progresses in the development of hard and soft magnetic materials and their production processes offer new possibilities to further improve electric energy converters. For permanent magnets remaining challenges are the dependence on critical rare earth elements and the limited possibility to optimize the microstructure to approach theoretical predictions of micromagnetism. Equally important is the minimization of magnetic losses in soft magnetic cores. Innovative synthesis processes like high-throughput experiments and additive manufacturing by laser powder bed fusion offer new degrees of flexibility. These allow optimized alloy compositions and microstructures as well as novel topological structures and multilayer composites. Selected examples for different hard and soft magnetic prototypes and their performance will be presented.
