Fe-Si基合金是一种广泛应用的软磁材料。近年发展起来的纳米微晶Fe_(73.5)Cu_1Nb_3Si_(13.5)B_9合金(即Finemet)具有优良的软磁性能,它由粒径10～20nm的α-Fe(Si)晶粒和剩余非晶相组成。许多工作表明这类材料的优良软磁性能与纳米量级大小的晶粒和传递交换耦合作用的界面有关。另外,Finemet是带状材料,其应用受到一些限制。文献[1]报道了通过机械合
Fe-Si-based alloy is a widely used soft magnetic material. The Fe_ (73.5) Cu_1Nb_3Si_ (13.5) B_9 alloy (Finemet), which has been developed in recent years, has excellent soft magnetic properties and is composed of α-Fe (Si) . Much work has shown that the excellent soft magnetic properties of these materials are related to nanoscale-sized grains and interfaces that exchange exchange coupling. In addition, Finemet is a ribbon material, its application is subject to some restrictions. Literature [1] reported through the mechanical combination
