摘要: 本文測量了Fe76Pr16B8燒結永磁體的室溫各向異性場HA=85KOe,磁晶各向異性常數K=4.2×107erg/cm3;磁體的磁能積已達到37MGOe。研究了各種工藝因素,諸如燒結溫度,回火溫度與時間等對燒結磁體性能的影響。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.
