The optimisation of production routes and the development of novel high-performance hard and soft magnetic materials require accurate knowledge of phase selection and microstructure evolution processes. Containerless solidification by electromagnetic levitation is applied as a powerful technique for revealing metastable phase formation in undercooled melts of Fe-Co, Fe-Ni soft magnetic and Nd-Fe-B hard magnetic alloys. Tight relations between space- and ground-based undercooling experiments and the production methods of high-performance permanent magnets are established. Undercooling experiments under microgravity conditions were carried out with the TEMPUS facility during parabolic flight campaigns. For soft magnetic Fe-Co alloys, significant effects of microgravity on the critical undercooling of metastable phase formation were discovered. Microstructure modifications and metastable phase formation as functions of undercooling were elucidated for Nd-Fe-B alloys. This may affect the production processes of hard magnetic materials based on rapid solidification. Modelling of solidification, fluid flow and heat transfer provide predictive tools for microstructure engineering from the melt. They are developed as a link between undercooling experiments under terrestrial and microgravity conditions and the production routes of magnetic materials.
