? 2022 Elsevier B.V.In the present work, the Nd9Fe85B6?xPx (x = 0–0.3) magnets were prepared via melt rapid quenching method. The P addition greatly improved the microstructure and magnetic properties. The study shows that the P addition increased the nucleation resistance of α-Fe, and hindered the precipitation of the α-Fe phase. The distribution of P in the Nd9Fe85B5.9P0.1 permanent alloys was characterized by the three-dimensional atom probe (3DAP) technique. Experimental results demonstrated that the P element is mainly concentrated at the grain boundary, inhibiting the growth of soft and hard magnetic crystals. The maximum energy product (BH)max of 20.0 MGOe and coercivity Hci of 6.34 kOe were obtained with the P content at x = 0.1, these values were larger than those of Nd9Fe85B6 alloys, with (BH)max = 17.7 MGOe and Hci = 5.61 kOe. The improvements of magnetic properties originate from the enhanced domain-wall-pinning strength and exchange coupling between the soft and hard phases.
