Abstract

Abstract

Room temperature anisotropy field of 85KOe and magneto-crystalline an-isotropy constant of 4.2×10⁷ erg/cm³ for sintered Fe₇₆Pr₁₆B₈ bulk permanent magnets were measured.The energy product of the sintered magnet is up to 34MGOe.The influences of process factors such as sintering temperature and annealing temperature and time etc. on magnetic properties were studied.
