Abstract

High-performance α-Fe/Pr₂Fe₁₄B-type nanocomposite magnets based on the compositions of Pr₈Fe ₈₆B₆ microalloyed with Co, Nb and C were fabricated by direct melt spinning. The coercivity was greatly improved from 5.5 kOe for the Pr₈Fe₈₆B₆ ribbons to 7.4 kOe for the Pr ₈Fe₈₅NbB₅C ribbons. The balanced high coercivity and remanence were obtained in Pr₈Fe₇₅Co ₁₀NbB₅C ribbons due to the Co substitution for Fe, which led to the significant improvement of magnetic properties in these ribbons. A remanence ratio of 0.82, a coercive field of 6.6 kOe and a maximum energy product of 26.2 MGOe in melt-spun Pr₈Fe₇₅Co ₁₀NbB₅C ribbons were obtained at room temperature.
