Effects of thermal demagnetization in air on the microstructure and organic contamination of NdFeB magnets
Laura Grau, Rosario Moreno López, Pierre Kubelka, Fabian Burkhardt, Tomaž Tomše, Spomenka Kobe, Carlo Burkhardt
Izvirni znanstveni članek
Oznake: razmagnetenje;magnetic scrap;thermal demagnetization;organic contamination;
Demagnetization is an essential step for the demounting and safe handling of end-of-life NdFeB. Thermal demagnetization in air is a straightforward option to demount adhesive-fixed or segmented magnets. However, this process is suspected to increase the uptake of contaminants like O, C and Zn from c ...

Nd-Fe-B-type permanent magnets, containing approximately 30% critical rare-earth elements by weight, are essential components in renewable energy systems (e.g., wind turbines, hydroelectric generators) and electric vehicles. They are also critical for consumer electronics and electric motors in prod ...

Grain-boundary-engineering of recycled Nd–Fe–B magnets from single-phase RE [sub] 2Fe [sub] 14B powder via rare-earth–Cu alloys
Mihaela Rebernik, Tomaž Tomše, Zoran Samardžija, Carlo Burkhardt, Laurence Schieren, Boštjan Markoli, Kristina Žužek Rožman
Izvirni znanstveni članek
Oznake: Nd–Fe–B magnets;recycling;rare-earth–Cu alloy;spark-plasma sintering;
For the purpose of creating more resource-efficient Nd–Fe–B magnets, RE2Fe14B single grains were recycled, and the Nd-rich secondary phase was replaced with binary and ternary rare-earth–Cu alloy additions. The effect on the microstructure evolution and the magnetic properties of such recycled magne ...

Rare-earth-based permanent magnets are key elements for today’s technologies. Their recycling is crucial for securing the supply of critical raw materials and ensuring a sustainable circular economy in magnet production. In this study, hydrogen decrepitated NdFeB powders recovered from end-of-life m ...
