【摘要】 本文通过对纳米晶软磁合金Fe-Zr-Nb-B磁性能的研究,得知当合金成分配比为Fe85.5Zr2Nb4B8.5且退火40min后合金的磁性能是最佳的。其磁导率为60,000(1kHz),饱和磁感应强度为1.64T,磁致伸缩几乎为零。合金的铁损也很低,在1.4T、50Hz时低至0.09W／kg,这个值比Fe-Si-B系非晶合金要低很多。因此Fe-Zr-Nb-B合金很适合做杆式变压器材料。更多还原

【Abstract】 The soft magnetic properties of the nanocrystalline Fe-Zr-Nb-B alloys have been investigated. The best soft magnetic properties have been obtained for the Fe85.5 Zr2 Nb4 B8.5 alloy. The alloy shows a high permeability of 60,000 at 1kHz, a high magnetic induction of 1.64T and zero magnetostriction, simultaneously. The alloy also exhibits a very low core loss of 0.09 W/kg at 1.4T and 50Hz, which is extremely lower than that of Fe-Si-B amorphous. The nanocrystalline Fe-Zr-Nb-B alloy is therefore suitable for a core material for pole transformers.更多还原
