Abstract
Abstract—The evolution of the multiscale hierarchical structure of an amorphous melt-quenched Fe70Cr15B15(Sn) alloy with a low tin content is studied. The fractal ordering of the alloy ribbon surface indicates the presence of localized structural states, which are large-scale recrystallization centers. The tin microalloying of the ribbon contact surface changes the topology of the localized states, which leads to a change in the scenario of transformations and to a decrease in the phase-transformation temperature. The character of structural ordering is reflected on the shape of fractal dimension spectra. The fractal dimension is reduced at the stages of vitrification and nanocrystallization.
