N2 - The structure of melt-spun, crystallographically isotropic Fe84Nd10B6 alloy ribbon has been studied by high-resolution transmission electron microscopy. The ribbon was spun so as to give a nanocrystalline structure, which led to enhancement of remanence and energy product but, owing to the low Nd content and consequently high Fe concentration, the alloy contained magnetically soft α-Fe particles, in addition to the stoichiometric Fe14Nd2B phase. The identification of the phases by lattice imaging and energy-dispersive microanalysis is presented and the relationship between the microstructure and the enhanced magnetic properties is briefly discussed.
