| Abstract | The structure and magnetic properties of NdxFeP92-xBS and Nd10Fe76B8-yTi6+y alloys prepared by mechanical alloying (MA) and subsequent annealing have been studied. It has been found that the exchange interaction between a soft alpha-Fe and a hard magnetic Nd2Fe14B phase results in a significant enhancement of the remanence for x < 12. The best values of 4 pi M-r = 8.1 kGs, H-i(c) = 21.1 kOe and (BH)(max) = 14.1 MGOe are obtained for the series of NdxFe92-xB8 with x = 16. For the series of Nd10Fe76B8-yTi6+y, when 0 less than or equal to y less than or equal to 6, the main phase Nd2Fe14B is formed and accompanied by Nd2O3. Fe2Ti and Nd-rich phases. In the present experimental investigation, the occupation state of Ti in the MA samples for 0 less than or equal to y less than or equal to 6 has been considered. The intrinsic coercivity reaches up to more than 11 kOe for 4 less than or equal to y less than or equal to 6. It is evident that the addition of Ti is favourable for the enhancement of the intrinsic coercivity in Nd-Fe-B alloys with a low level of Nd, which is mainly due to the coexistence of the Nd-rich phase and the hard magnetic phase with the structure of Nd2Fe14B containing Ti, combined with the suppression of alpha-Fe, for the samples with 0 less than or equal to y less than or equal to 6.
