摘要
采用熔体快淬及热处理工艺制备Nd10.1Fe76.2Co4.5Zr3B6.2永磁材料,研究了制备工艺参数和热处理工艺对材料结构和磁性能的影响。结果表明,粘结磁体的磁性能与熔体快淬和热处理工艺密切相关,快淬速度为20m/s的薄带经690℃×4m in退火处理可得到最佳磁性能:Br=0.714T、JHc=698kA/m、(BH)max=82.0kJ/m3。
Nanocrystalline Nd10.1Fe76.2Co4.5Zr3B6.2 ermanent magnet materials were prepared by melt-spun and subsequent heat treatment. Influences of the fabrication process and heat-treatment on the materials structure and the magnetic properties were studied. The results show that magnetic properties of bonded magnets are affected by changing the meltspun process parameters and heat treatment. The optimum magnetic properties can be obtained with heat-treating the ribbons （20m/s）at 690℃ for 4min. The remanence （Br） , intrinsic coercivity （JHc ） and maximum magnetic energy product （BH） max are 0. 714T,698 kA/m and 82.0kJ/m^3 respectively.
