零磁致伸缩非晶合金(Fe_(0.06)Co_(0.94))_(75)Si_(10)B_(15)有好的软磁性能,但稳定性差、影响其实用价值。本文以该合金为基,将一部分Co用(Ni+Nb)替代,制得[Fe_(0.06)Co_(0.85)(Ni+Nb)_(0.09)]_(75)Si_(10)B_(15)系非晶合金。通过合金的晶化温度、居里温度、比重、电阻率、静态和动态磁参数的测量及热稳定性实验的结果表明:同时添加Ni和Nb对提高合金磁性能,改善热稳定性都有良好的效果;对Ni、Nb配比适当的合金,其磁性能优于坡莫合金,适宜制作各种磁头芯片、磁屏蔽、变压器、电源变换器等多种电子器件的铁芯材料。
Zero magnetostrictive amorphous alloy (Fe_ (0.06) Co_ (0.94)) _ (75) Si_ (10) B_ (15) has good soft magnetic properties, but its stability is poor, which affects its practical value. Based on this alloy, a part of Co was replaced by (Ni + Nb) based on this alloy, and the results showed that [Fe 0.06 Co 0.85 Ni + Nb 0.09 11 75 Si 10 B 15 ) Department of amorphous alloys. The results of the measurement of the crystallization temperature, the Curie temperature, the specific gravity, the resistivity, the static and the dynamic magnetic parameters and the thermal stability experiments show that the addition of Ni and Nb simultaneously improves the magnetic properties and the thermal stability of the alloy Of the effect; Ni, Nb ratio of the appropriate alloy, the magnetic properties superior to Permalloy, suitable for the production of a variety of head chip, magnetic shield, transformers, power converters and other electronic devices of the core material.
