本文介绍了一类新奇的由非晶母材制备成的钠米复合合金(nanocrystalline composite alloy)。它们的成分与二十世纪七、八十年代研制的玻璃合金(metallic glass)十分接近。与玻璃合金形成鲜明对比的是这种材料有极佳的高温结构稳定性,有高饱和磁化强度、低矫顽力、低磁致伸缩和高导磁率。下面就钠米合金和非晶合金的磁性能、结构参数、加工特点和应用进行了比较。 前言 This article presents a novel class of nanocrystalline composite alloys made from amorphous base metal. Their composition and the twentieth century the development of the seventies and eighties, the glass (metallic glass) is very close. In stark contrast to glass alloys, this material has excellent high temperature structural stability, high saturation magnetization, low coercivity, low magnetostriction and high permeability. The following nano-alloy and amorphous alloy magnetic properties, structural parameters, processing characteristics and applications were compared. Foreword
