メカニカルアロイング法により作製したFe-Co-Si合金の磁気特性

抄録

Fe-Si, Fe-Co, and Fe-Co-Si powders were prepared by the mechanical alloying process, starting with elemental powders. Their magnetic properties and x-ray diffraction patterns were investigated. Two kinds of milling processes were adopted to obtain higher magnetization for (Fe_1.0-xCo_x)₇₅Si₂₅. A magnetization of 184.6 emu/g at 20 kOe was obtained for a sample prepared by milling a mixture of Fe and Co powders for 30 hours, then milling it with Si powder for a further 10 hours.
