摘要：In order to increase the intrinsic coercivity of the Nd-Fe-B magnets, the aging process optimization had been carried out. The results showed that more than 17 kOe intrinsic coercivity could be obtained by the aging process optimization. The microstructures and the fractures of the Nd-Fe-B magnets treated by the optimized aging process were also investigated by optical microscope, thermal field emission scanning electron microscopy and energy disperse spectroscopy. It was showed that the thin, continuous and smooth Nd-rich layer along the boundaries of the main crystal phase Nd2Fe14B could be formed by the optimized aging treatment and it resulted in the increase of the intrinsic coercivity of the Nd-Fe-B magnets. © (2014) Trans Tech Publications, Switzerland.
