Abstract

Permanent magnets, composition Nd4Fe96−x B x (x=10–21), were made by rapid quenching followed by crystallization. The effects of B concentration and annealing time on the magnetic properties and phase compositions were studied by Mössbauer spectroscopy and magnetic measurements. The stripping method was adopted to obtain the subspectral area of each Fe phase. Optimum magnetic properties are obtained for the composition Nd4Fe77B19 annealed at 670°C for 3 minutes. Then the remanence is 12.0 kGs, the intrinsic coercivity 3.2 kOe, and the maximum energy product 12.6 MGOe. The crystalline phases are Fe3B, Nd2Fe14B and α-Fe with volume percentages of 60%, 36%, and 4%, respectively.
