We have used a high-energy ball mill to prepare single-phased nanocrystalline Fe, Fe 90 Ni 10 , Fe 85 Al 4 Si 11 , Ni 99 Fe 1 and Ni 90 Fe 10 powders. We then increased their grain sizes by annealing. We found that a low-temperature anneal (T < 0.4 T m ) softens the elemental nanocrystalline Fe but
