本文通过铜模吸铸法和单辊甩带法分别制备出一系列楔形试样和非晶条带试样, 系统研究了稀土金属Y对Fe78Si9B13合金非晶形成能力及其软磁性能的影响. 结果表明, 少量Y取代 Fe-Si-B 非晶合金中的Fe 可大大提高该合金的非晶形成能力并促进过冷液相区的产生. 当Y含量为3 at.%时, 合金具有最大的非晶形成能力, 其临界厚度为313 μm, 相应的非晶过冷液相区宽度达到65 K. 该系列非晶合金具有优良的软磁性能, 其矫顽力(Hc)均低于200 A/m, Y含量为1 at.%时, 饱和磁感应强度(Bs) 达到最大值1.67 T.Addition of rare earth elements can significantly improve the glass forming ability of Fe-based alloys. But the magnetic domain that most of the rare earths possess themselves always worsens soft magnetic properties of the alloys. By contrast, the rare earth element Y does not have this kind of magnetic domain itself, and is an ideal candidate to add to the Fe-based amorphous alloys as soft magnetic materials. In order to systematically study the effect of partial substitution of Fe in Fe78Si9B13 alloy with rare earth element Y on glass forming ability and soft magnetic properties, a series of wedge-shaped specimens and amorphous ribbons are prepared by copper mold suction casting and melt spinning respectively. It is found that the replacement of Fe by minor Y enhances the glass forming ability of the alloy. When 3 at.% Fe is replaced, the critical thickness and supercooled liquid region of the amorphous alloy reach their maximum values, 313 μm and 65 K, respectively. The amorphous alloys have excellent soft magnetic properties: coercive force (Hc) all bellow 200 A/m and saturation magnetic induction (Bs) all above 1.30 T. Specially, Bs reaches a maximal value, 1.67 T, when 1 at.% Fe is substituted.
