Fe-B nanomaterials by mechanochemical synthesis: A Mossbauer study

The process of phase formation during short-term (80 and 120 min) high-energy ball milling of Fe84B16, Fe80B20, and Fe70B30 powder mixtures was studied by Mossbauer spectroscopy. Hyperfine field B-hf on the nuclei of resonant atoms as a function of the number of boron atoms (n(B)) in the nearest neighborhood of Fe atoms was also found to be a linear function of n(B) and for n(B) = 5-11: B-hf = 33.7 - 2.7n(B).
