以非晶前驱体为基础，发展了一类新型的纳米晶复合合金。它们的成分与20世纪70 - 80年代开发的金属玻璃非常相似。与金属玻璃相比，这些材料在高温下提供极好的结构稳定性、增加的饱和磁化强度、低磁导率、低磁致伸缩和高磁导率。本文比较和对比了纳米晶和非晶合金的磁性和结构特性、加工特性和实用性。
A novel class of nanocrystalline composite alloys has been developed from amorphous precursors. Their composition bears close resemblance to the metallic glasses developed during the 1970–80s. In contrast to metallic glasses, these materials offer superb structural stability at high temperatures, increased saturation magnetization, low coercivity, low magnetostriction, and high permeability. This article compares and contrasts the magnetic and structural properties, processing characteristics, and utility of nanocrystalline and amorphous alloys.
