Abstract

The effects of Nb addition on the hard magnetic properties and microstructure evolution in Nd₈Fe_78-xCo₈B ₆Nb_x and Nd₁₂ Fe_82-x B ₆Nb_x nanocrystalline alloys are presented. Low Nd containing alloys consist of α-Fe and Nd₂Fe₁₄B phases. The Nd₁₂Fe_80.5B₆Nb_1.5 alloy probably contains NbFeB phase besides the α-Fe and Nd₂Fe ₁₄B phases. It is found that Nb atoms tend to enrich at grain boundary region, resulting in refined microstructure and significantly improved coercivity over a range of conventional Nd-Fe-B alloys.
