Anisotropic NdFeB/SmCoCuFeZr composite bonded magnets were prepared by warm compaction process. The effects of adding SmCoCuFeZr magnetic powder on the properties of anisotropic bonded NdFeB magnet were investigated in this work. The results show that, both magnetic properties and temperature stability of the bonded magnet can be improved by adding fine SmCoCuFeZr magnetic powder. In the present study, the optimal content of SmCoCuFeZr magnetic powder was about 20 wt.%, in this case, the B-r, H-cj, and (BH)(max) of the NdFeB/SmCoCuFeZr composite magnet achieved 0.943 T, 1250 kA/m, and 168 kJ/m(3) , respectively. 2017 Published by Elsevier B.V. on behalf of Chinese Society of Rare Earths.
