The melt-spun ribbons of Pr-Fe-Co-W-B system alloys were prepared by single roller rapid-quenching method. The effects of composition , wheel velocity and heat-treatment on the magnetic properties were investigated. The Pr 9 Fe 76.7 Co 8 W 0.3 B 6 ribbon prepared at a wheel velocity of 15.0 m/s were crystallized by heat-treatment , and the optimum heat-treatment condition was found to be at 600 ℃ for 3 min , then the value of (BH) max was 148.5 kJ/m 3 . The temperature coefficients of J r and H cJ for the ribbons crystallized from the amorphous Pr 9 Fe 76.7 Co 8 W 0.3 B 6 alloy were α (J r )= - 0.03 %/ ℃ (reversible)and α (H cJ )= - 0.45 %/ ℃ (irreversible) , respectively. The value of (BH) max for the compression molding Pr 9 Fe 76.7 Co 8 W 0.3 B 6 isotropic bonded magnet prepared by using the ribbons annealed at 600 ℃ for 3 min is 86.00 kJ/m 3 and the density is 6.16 Mg/m 3 .
