Zlitine na osnovi sistema Sm-Fe, intersticijsko modificirane z dušikom, imajo velik potencial kot trajni magnetni materiali. Optimalne magnetne lastnosti lahko dosežemo s pravilno obdelavo zlitine, ki pa temelji na poznavanju materiala. Primerjali smo zlitini sestave ▫$Sm_{13,8}Fe_{82,2}Ta_{4,0}$▫ i ...

An alloy of composition ▫$Sm_{13,8}Fe_{82,2}Ta_{4,0}$▫ was compared with a conventional ▫$Sm_{13,7}Fe_{86,3}$▫ material in order to assess its potential as a permanent magnet mataerial. The optimum conditions necessary to provide the highest coercivities using the HDDR process and for the HDDR proce ...

Fully dense spark plasma sintered recycled and fresh HDDR Nd-Fe-B nanocrystalline bulk magnets were processed by surface grain boundary diffusion (GBD) treatment to further augment the coercivity and investigate the underlying diffusion mechanism. The fully dense SPS processed HDDR based magnets wer ...
