铁基软磁非晶合金和块状金属玻璃的研究进展

The development of Fe-based soft magnetic amorphous and bulk metallic glassy alloys

为了研发新型软磁材料,铁基非晶合金带材、铁基块状金属玻璃和铁基纳米晶材料等非晶态合金材料被给予了深度关注和广泛研究。近些年,人们在铁基非晶态合金材料中获得了高饱和磁感应强度、低矫顽力、高磁导率和低铁芯损耗,使之展现出优越的软磁性能,并且已经有商业化成果问世。介绍了铁基软磁非晶合金和块状金属玻璃的发展概况、归纳了一些最新的研究成果,并展望了其发展趋势。

As guide lines to develop a new soft magnetic material,much attention has been paid to the three development ways by utilizing nonequilibrium phases of amorphous,nanocrystalline and bulk glassy alloy phases.Recently,Fe-based amorphous alloys with excellent soft magnetic properties such as high saturation magnetization,low coercivity,high permeability and low core losses have been synthesized and commercialized.This paper aims to clarify the recent development of Fe-based soft magnetic alloys and bulk metallic glass,to summarize some important research achievement and to prospect the research tendencies for Fe-based soft magnetic amorphous/glassy alloys.
