Description
Exchange-spring magnets of NdxFe86-xCo8V1B5 and NdxFe85-xCo8V1B6 (x=6−9) alloy ribbons were prepared by the single-roller rapid quenching method. The effects of the composition and annealing treatment on the magnetic properties were investigated. The values of (BH)max and HcJ were found to increase with the Nd content, while, the value of Br decreased slightly. The optimum preparation conditions and some properties were as follows: composition, Nd9Fe76Co8V1B6; roller speed, 20 m/s; annealing condition, 675°C × 0 min; magnetic properties: (BH)max = 165.4 kJ/m3, HcJ = 455.4 kA/m, HcB = 423.3 kA/m, Br= 1.11 T, α (Br)= −0.067 (%/°C), β (HcJ) = −0.33 (%/°C), Hk/HcJ × 100 = 44.7%, Tc = 448°C. From TEM observation, the particle size of this ribbon was determined to be 20 to 30 nm.
