Abstract
The structural and magnetic properties of nanostructued Fe–33
at.%Si alloy powders were investigated. Commercial Fe–33
at.%Si alloy powders (Hoeganaes Co., USA) with 99.9% purities were used to fabricate the nanostructure Fe–Si alloy powders through a high-energy ball milling process. The alloy powders were fabricated at 400
rpm for 50
h, resulting in an average grain size of 16
nm. The nanostructure powder was characterized by fcc Fe
3Si and hcp Fe
5Si
3 phases and exhibited a minimum coercivity of approximately 50
Oe.
