Abstract

We have investigated the microstructure and the coercivity of Nd ₁₀Fe_77.5B_12.5-xM_x (M=Zr, Nb, x=0∼3) bulk nanocomposite magnets in order to obtain insight into the factors responsible for the coercivity increase by the addition of Zr and Nb. The volume fraction of the Nd₂Fe₁₄B phase is found to increase appreciably with the Zr and Nb addition, indicating that the Zr/Nb addition is effective in the suppression of a second phase. The increase of the coercivity in both alloys is understood to be due to the increase of the volume fraction of the Nd₂Fe₁₄B hard phase.
