摘要：
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 50h, resulting in an average grain size of 16nm. The nanostructure powder was characterized by fcc Fe3Si and hcp Fe5Si3 phases and exhibited a minimum coercivity of approximately 50 Oe. (c) 2005 Elsevier B.V. All rights reserved.
