Paper Title:
Magnetic Properties and Structures of HDDR Nd2Fe14B-Based Magnet
  Abstract

The phase structures and the magnetic properties of HDDR magnet powders produced from the alloys with a nominal composition of Nd14FebalCo14B6.5AlxZry (x=0, ~0.35; y= 0, ~0.35) have been studied. The variation of the magnetic properties of the bonded magnets with HD temperature and DR temperature was investigated. A scruple addition of Al is useful to improve the magnetic properties of HDDR bonded magnets. And the composite addition of a little Al and Zr can further enhance the magnetic properties. As x = 0.15 and y = 0.1, the magnet properties can reach iHc = 990 kA/m, Br = 0.86 T and (BH)max = 118.4kJ/m3. The reasons for the enhancement of the magnetic properties by the composite addition of a little Al and Zr are analyzed.
