Abstract

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, M_r/M_s > 0.5, has been shown to be due to ultra fine grain size below 20 nm.
