Preparation of Rapidly Quenching (Nd, Pr) 12 (FeCoZr) 82 B6 Alloy and Magnetic Properties of Bonded Magnets
J OURNAL OF RARE EARTHS Vol.22, No.4, Aug.2004, p.497，-0001，（）：
The optimum quenching rates and annealing conditions to prepare near stoichiometrical (Nd,Pr)12 (FeCoZr) 82B6 bonded magnets were investigated by using sub-overquenching and post annealing method. The quenching rates, annealing temperatures, and annealing time directly influence the microstructure and magnetic properties of alloy ribbons. The opti-mum magnetic properties of bonded magnets are achieved by melt spinning at 24ms-1wheel surface speed, annealing at 655℃ for 10 min, and bonding with 3.25% (mass fraction) epoxy. The best magnetic properties of remanence Br, in-trinsic coercivity Hci and maximum energy product (BH) max are 0. 669 T, 811 kA•m-1, and 75kJ •m-3, respectively.
