【 摘 要 】

The microstructure and magnetic properties of nanocrystalline Fe-Si soft magnetic material fabricated by high energy vibratory milling are investigated. Fe-Si x wt% (x = 1.78, 3.51, 3.80, 5.08, 6.06, 6.98, 8.04) compositions are studied, with the 3.5 wt% case being used as a model system to investigate effects of processing time. Xray diffraction (XRD) measurements indicate that the Si is fully in solution in the Fe lattice and no ordered phases are present. It is shown that microstructural evolution is accelerated compared with previously observed lower energy milling processes of iron-based alloys. It is also shown that magnetic properties are in disagreement with the formulas derived from the random anisotropy model, and explanations are provided for potential sources of this discrepancy in this and other reported work.
