Abstract: The origin of magnetic hardening has been examined in melt-spun Fe 76 Nd 16 B 8 samples heat-treated at around 700°C. Microstructure studies show the same phases as in sintered magnets consisting of Fe 14 Nd 2 B, Fe 4 NdB 4 and two high-Nd content phases. These phases exist in both equiaxed and faceted crystallites of submicron size. Lorentz microscopy shows domain walls which end at grain boundaries indicating that they are pinned there.
