本文系统地研究了快淬工艺条件对含少量硅的Nd-Fe-B合金纳米晶晶粒尺寸和磁性能的影响。建立并讨论了剩磁、矫顽力与晶粒尺寸之间的关系。观察到的增强的剩磁（Mr/Ms> 0.5）已被证明是由于低于20 nm的超细晶粒尺寸。
The paper presents the results of a systematic investigation of the influence of melt-spinning processing conditions on the grain size in the nanocrystalline range and on the magnetic properties of Nd-Fe-B alloys with small silicon additions. The relationships between remanence, coercivity and grain size are established and discussed. The enhanced remanence observed,Mr/Ms> 0.5, has been shown to be due to ultra fine grain size below 20 nm.
