Good soft magnetic properties were obtained in mechanically alloyed Fe-Si powders. The Fe75Si25 powder annealed at 450 °C possessed a magnetization of 149 Am2/kg and a coercivity of 0.2 kA/m. The coercivity model for soft magnetic nanocrystalline materials could be well applied to the Fe-Si powders in this work. The mechanically alloyed Fe-Si possessed significantly higher magnetic permeability than that of commercially available Fe-Si powder. The permeability of the mechanically alloyed Fe75Si25 powder was comparable with that of mechanically alloyed pure Fe powder. Considering of lower density and better chemical stability of Fe-Si, the mechanically alloyed Fe-Si may be interesting for soft magnetic application including magnetic shielding and electromagnetic noise suppression. | Source Title: | Journal of Alloys and Compounds | URI: | http://scholarbank.nus.edu.sg/handle/10635/107123 | ISSN: | 09258388 | DOI: | 10.1016/S0925-8388(00)01234-2 |
