摘要: We present the effects of terbium additives upon microstructure and magnetic properties Fe83Ga17Tbx alloys (x = 0, 0.2, 0.4, 0.6, 0.8), prepared by vacuum electric arc-melting directional solidification techniques. Experiments indicate that small amounts more than double saturation magnetostriction a [110] textured Fe83Ga17 alloy with λ = 72 × 10−6 lower field. The pronounced increase in stems from appearance [100] texture polycrystalline alloys. It is verified textures are enhanced introduction atoms preferentially residing Tb-rich intergranular phase.
