Changes to the surface of corrugated platinum foil under load

Changes in the surface layers of the corrugated Pt foils, considered as multiscale diffraction gratings, under tensile stress are studied. The analysis of transformations in the structure and the degree of its ordering at different stages of material loading, up to its destruction, is carried out. With a help the concept of the multifractal formalism, a criterion for the effectiveness of these foils is proposed.
