Abstract

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.
