摘要
The present invention provides a tempering process for sintered Nd—Fe—B permanent magnet material, which optimizes the microstructure of the Nd—Fe—B magnet and improves intrinsic coercive force and its consistency by increasing the cooling rate after tempering. After heating to a temper temperature, the magnetic material is cooled in a cooling liquid within a cooling chamber into which a pressurized cooling gas is introduced.
