SEM identification of the amorphous state of Fe−B ribbons

Аннотация

Based on X-ray diffraction and electron microscopy data on morphological inhomogeneities at the interfaces in Fe−B ribbons, the boundary boron concentration separating the crystal and amorphous states upon spinning (~10 at %) is established. A modulated isotropic stochastic wave structure is detected, the relaxation of which can be presented as spinodal decomposition.
