    摘要:

    采用電弧爐快淬和晶化退火工藝制備高性能NdxFe90.5-xZr3.0B6.5（F8．5=11．5）快淬磁體。結(jié)果表明，Zr的添加顯著提高磁體的磁性能，Nd含量可以明顯提高磁體的磁性能，X由8．5增加到10．5時(shí)，NdxFe90.5-xZr3.0B6.5磁體的磁能積由75kJ／m^3升高到114kJ／m^3，接近于美國Magnequench公司的MQP-B磁粉性能。

    Abstract:

    High performance NdxFe90.5-x Zr3.0B6.5(x=8.5~11.5)ribbons were produced by arc melt spinning and then annealing.It is found that a proper amount of Nd addition can obviously optimize the magnetic properties of the samples.The energy product of NdxFe90.5-xZr3.0B6.5 ribbons is increased from 75 kJ/m3 for x=8.5 to 114 kJ/m3 for x=10.5 which is closed to that of America MQP-B magnets.In addition,it can be seen that Zr dopants can significantly improve the magnetic properties of the ribbons.
