成分为FeSi_(9.6)Al_(15.4)的合金由于K、λ趋于具有良好的直流特性,该合金电阻率高(p=90μΩ·cm),高频下仍保持较好的磁性和较低的损耗,在金属软磁材料中具有很高的硬度(Hv=500),适合用作磁头铁芯材料、尤其视频磁头铁芯,但它致命的弱点是不能加工,这严重影响了FeSiAl合金的广泛使用.近年来国内外在采用快速淬火方法制备合金带材取得了很好的效果.本文介绍作者采用快速淬火方法制备FeSiAl合金带,观 Alloys with FeSi_ (9.6) Al_ (15.4) alloys tend to have good DC characteristics because of K and λ. The alloys have high resistivity (p = 90μΩ · cm), good magnetic properties at high frequencies and low Loss, high hardness in metal soft magnetic materials (Hv = 500), suitable for use as a head core material, in particular a video head core, but its lethal weakness is not machinable, which severely affects the wide range of FeSiAl alloys Use.In recent years, rapid quenching at home and abroad in the preparation of alloy strip obtained good results.This article describes the rapid quenching method used to prepare FeSiAl alloy strip, the concept
