摘要：
Coercivity This study was aimed at the improvement of SmFe3-based alloys prepared by means of melt-spinning. A systematic study was carried out on (Sm1-xZrx)(Fe0.75Co0.25)(3) (x = 0 -0.4) alloys melt-spun at a wheel speed of 50 m/s and annealed at 773 -1173 K. SmFe3-based melt-spun ribbons with a rhombohedral structure were prepared from the (Sm1-xZrx) (Fe0.75Co0.25)(3) (x = 0 -0.4) alloys. The addition of zirconium increased the coercivity and enhanced the remanence of the melt-spun ribbons. However, the Curie temperature slightly decreased with increasing zirconium content. The optimally annealed alloys, with a composition of (Sm0.7Zr0.3) (Fe0.75Co0.25)(3), achieved a coercivity of 7.8 kOe, a remanence of 6.0 kG, and a Curie temperature of 680K.
