摘要：

N8.5Fe75Co5Cu1Zr3Nb1B6.5 bonded magnet was prepared by melt-spinning (v(s) = 18 m/s) and subsequent heat treatment (670 degreesC, 4 min). Excellent magnetic properties of the bonded magnet were achieved: B-r = 0.68T, H-i(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 isctropic saturation remanence ratio M-r/M-s is 0.83.
