Changes in the defective structure of the surface of a Fe$_{77}$Ni$_{1}$Si$_{9}$B$_{13}$ metal glass ribbon under the influence of hydrostatic pressure and isothermal annealing

The features and generality of the effect of hydrostatic pressure and annealing on the surface relief of the contact and non-contact side of the Fe$_{77}$Ni$_{1}$Si$_{9}$B$_{13}$ metal glass ribbon are revealed. The relationship between transformation of the ribbon surface inhomogeneities under these effects and possible formation of nanocrystalline regions are analyzed. We found that the evolution of the surface inhomogeneities at the contact side of the ribbon after annealing procedure leads to appearing of discrete-sized fractions in these regions.
