摘　　要：介绍了N48H高性能烧结NdFeB永磁材料的开发过程。通过调整添加元素,采用先进的片铸(SC)工艺、氢爆碎(HD)+气流磨(JM)制粉技术、密封式高磁场取向成型技术,结合适当的防氧化措施,制备出Br=1.418T,Hcb=1079kA/m,Hcj=1376kA/m,(BH)max=379kJ/m3的高综合性能烧结NdFeB磁体。The process for producing N48H high-grade NdFeB magnet has been described in this paper. By adjusting doping elements and,adopting strip casting, HD technique, jet milling airtight moulding and proper oxidation protection measures, we have produced sintered NdFeB magnet with excellent overall properties of Br=1.418T, Hcb= 1079kA/m, Hcj= 1376kA/m and （BH）max=379kJ/m^3.
