摘要
Nd 8.5 Fe 75 Co 5Cu 1Zr 3Nb 1B 6.5 bonded magnet was prepared by melt spinning ( v s=18?m/s) and subsequent heat treatment (670?℃, 4?min). Excellent magnetic properties of the bonded magnet were achieved: B r=0.68T, i H c=620.3?kA/m, ( BH ) max =74?kJ/m 3. The addition of Cu and Zr elements shows to be advantageous in improving an intrinsic coercivity and squareness of hysteresis loop, as well as energy product. It has a remarkable remanence enhancement and the isotropic saturation remanence ratio M r/ M s is 0.83.
