Processing Sm-Fe(Ta)-N hard magnetic materials
Kristina Žužek Rožman, Paul J. McGuiness, Spomenka Kobe
Izvirni znanstveni članek
Oznake: HDDR;SmFeN;Ta;milling;
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 ...

High coercivities in HDDR processed Sm-Fe-Ta-N magnets
Kristina Žužek Rožman, Paul J. McGuiness, Spomenka Kobe
Izvirni znanstveni članek
Oznake: HDDR;SmFeN;Ta;coercitivity;milling;
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 ...

Oznake: SrFe$_{12}$O$_{19}$-based filaments;magnetic particles;polymers;polyphenylene sulphide;3D printing;magnetic field;
We describe the fabrication of SrFe$_{12}$O$_{19}$-based filaments, using polyphenylene sulphide (PPS) as the binder for the magnetic particles, and the subsequent printing of this filament with a 3D printer. PPS is an ideal polymer for applications in harsh environments, making it applicable for th ...
