电力技术用高Bs新型纳米晶合金

摘要

评述了国内外饱和磁感应强度Bs达1.8～1.94T以上并且工作磁通密度Bm达1.5 ～ 1.7T时的铁损优于细畴高取向硅钢的FeCuSiB(P)等系Fe基纳米晶合金的最新研究进展.重点介绍了新型Fe基纳米晶合金的成分、性能和影响性能的关键因素,讨论了国内对高Bs纳米晶合金的开发情况.%The recent advances were reviewed in Fe-based nanocrystalline alloy such as FeCuSiB(P) series alloys with Bs of 1.8-1.94T and Pc lower than that of refining domain, high grain orientation silicon steel when its working Bm reaches 1.5-1.7T. The component, property, and key factors affecting the performance of the new Fe-based nanocrystalline alloy were presented. Also, the domestic development situation of high-Bs nanocrystalline alloy was discussed particularly.
