采用深过冷结合铜型铸造法成功制备了具有纳米片层结构和优异软磁性能的Fe-B-M(M = Si,Cu)三元共晶合金块体。研究了Si和Cu元素对合金组织细化和软磁性能的不同影响。结果表明,当Si或Cu含量为1at. %加入到Fe-B共晶合金中。基于经典的随机各向异性模型,得到了内禀磁化率(HC)与片层间距(λ)之间的定量关系。
The bulk Fe-B-M (M = Si, Cu) ternary eutectic alloys with nano-lamellar structure and excellent soft magnetic properties were successfully prepared by undercooling combined with Cu-mold casting. Different effects of Si and Cu elements on the structural refinement and soft magnetic properties were studied. The results show that the lamellar spacing can be decreased to less than 50 nm with addition of Si or Cu of 1 at. % into the Fe-B eutectic alloy. Based on the classical random anisotropy model, a quantitative correlation between the intrinsic coercivity (HC) and the lamellar spacing (λ) was also obtained.
