In-situ grain-boundary diffusion in near-equilibrium Nd-Fe-B powders for high-coercivity reprocessed magnets
Tomaž Tomše, Fabian Burkhardt, Zoran Samardžija, Kristina Žužek Rožman
Izvirni znanstveni članek
Oznake: koercivnost;recikliranje magnetov;grain growth;
We demonstrate an in-situ grain-boundary diffusion strategy for enhancing the coercivity of reprocessed Nd-Fe-B magnets using near-equilibrium powder particles produced by intergranular fragmentation. A small addition (1 wt.%) of TbH3 leads to Tb enrichment at grain-boundary/shell regions, consisten ...

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 ...
