Abstract

Abstract

The preparation process of HDDR ternary NdFeB anisotropic powder was studied. The research results showed that the effects of desorption rate of hydrogen on the magnetic properties of HDDR ternary NdFeB anisotropy were remarkable, and slow desorption treatment was beneficial to the attainment of strong anisotropy. By the optimum HDDR treatment, the HDDR ternary NdFeB anisotropy bonded magnet with B_r of 0.78 T,_iH_c of 640 kA·m^-1 and (BH)_max of 84kJ·m^-3 can be obtained.
