磁性材料是最重要的功能材料之一,在工业和现代科学技术发展中、特别是电子技术发展中发挥着极其重要的作用。磁性材料的发展带动了电力电子技术等许多领域的发展。磁性材料的种类众多,按应用类型通常可分为永磁材料、软磁材料等。在电力及电讯技术的推动下,软磁材料的需求快速增长,软磁产业也随之得到快速发展。在软磁材料近百年的发展进程中,出现的比较有代表性的传统软磁材料有硅钢、铁氧体、坡莫合金等。
随着电子技术的发展,电子产品向小型化、轻量化和高性能方向发展,为减少、抑制、消除电磁污染和干扰的需要,要求软磁材料需要具有高饱和磁通密度、低损耗、高导磁、高稳定性、低成本等特性,这些对传统软磁材料提出了巨大的挑战。在此背景下,铁基软磁非晶/纳米晶合金因其原子呈长程无序排列的结构特征,使其具有较小的结构关联尺寸、很小的磁各向异性,因而具有很小的矫顽力,使其逐渐成为性能优异的新型软磁合金材料。同时,铁基软磁非晶/纳米晶合金具有更好的磁感应强度、更低的铁损率和更低的电能消耗,因此成为了一种新型的绿色节能材料。这些铁基非晶/纳米晶合金材料的出现,与传统的硅钢、铁氧铁等软磁材料相比,在很多应用领域具有更优异的综合磁性能和更佳的节能环保性,因此,成为了是一种极佳的对传统软磁材料的替代材料。实验表明,非晶的成分、制备工艺和随后晶化的方式都影响纳米晶的形成和以后的使用性能。传统的软磁产品型号一般采用107型号,产品尺寸为267/330/30(外径/内径/厚度)单位mm,其其组成以各组成元素的总原子量计,各组成成份的原子组成百分比为硅8.0-8.4%,硼2.0-2.4%,铜1.3-1.5%,铌5.65-5.69%,其余成分为纯铁Fe。
