| Abstract: | The ingot of Fe?Si?Al alloy was crushed and ground into plate and granular shaped powders. The powders were classified into several groups in the range from 7 μm to 105 μm by particle sizes. The inner magnetic hyperfine field decreased slightly with the decrease of a particle size and the magnetic field distribution changed between plate and granular particles. The estimation of the alloy deformation during powdering process were carried out on the base of the site occupation of iron atom observed by the Mössbauer spectra. |
