综述了软磁材料的研究现状,以及作者近年来在非晶、纳米晶以及软磁复合材料等高性能软磁材料方面的研究进展。基于放电等离子烧结技术,进行了Fe基非晶软磁材料的大尺寸工程化制备研究,成功制备致密大尺寸具有优异软磁性能的Fe76Si9B10P5非晶磁环。通过放电等离子烧结的加热速率控制放电脉冲强度,在低于Fe76Si9B10P5非晶玻璃转变温度以下,一步法实现Fe76Si9B10P5非晶合金的块体致密化与纳米晶化,实验结果表明,大的SPS脉冲电流促进纳米晶化形核过程,使晶化后的晶粒更加细小均匀。重点介绍了微胞结构软磁复合材料的制备原理、结构特点以及优异的电磁性能。最后展望了高性能软磁材料的应用前景以及重要研究方向。
Abstract：The environmental and energy problem more and more get the attention of the countries all over the world,energy conservation and emission reduction has become the focus of attention of the common humanity.Magnetic materials in the national economy is an important base materials,in recent years,appeared by electric drives and electronic control device of products of drive,automatic control and function of trend,the key is one of the core materials soft magnetic materials.Soft magnetic materials in various devices play energy transfer and conversion function coupling.Improve the efficiency and reduce the soft magnetic ferrite core material loss in energy saving and environmental pollution control has the great significance.This paper briefly introduces the current research status of soft magnetic materials and the progress in research of high performance magnetic materials such as the amorphous,nanocrystalline and soft magnetic composite by author in recent years.
