It is found that, compared with the vacuum sintering, the magnet sintering at argon protection has lower density, magnetic-energy product and remanence, but coerciveforces are higher. The magnet has more and bigger pores, and there obviously exist loose microstructure, the Nd-rich phases are clearly distributed along the grain boundaries mainly in the shape of lumpish and lamelliform.
