Abstract
A structural heterogeneity of a newly developed soft magnetic Fe₈₁.₂Co₄Si₀.₅B9.5P4Cu0.8 melt-spun alloy has been studied by transmission electron microscopy (TEM) and electron diffraction. Hollow-cone dark-field TEM imaging revealed that the density of coherent scattering regions in the as-quenched Fe₈₁.₂Co₄Si₀.₅B₉.₅P₄Cu₀.₈ alloy is as high as that in the Fe₈₅.₂Si₂B₈P₄Cu₀.₈ hetero-amorphous alloy (NANOMET®). According to the aberration-corrected high-resolution TEM, crystalline atomic clusters, typically of ∼1 nm in diameter, are densely distributed in an amorphous matrix of Fe₈₁.₂Co₄Si₀.₅B₉.₅P₄Cu₀.₈ alloy, while nanobeam electron diffraction detected weak Bragg reflections from Fe clusters with the body centered cubic structure. These results unambiguously reveal structural heterogeneity of the as-quenched Fe₈₁.₂Co₄Si₀.₅B₉.₅P4Cu₀.₈ alloy, which is similar to that observed in the NANOMET®.
