Visualitation of undulatory mass transfer in nearsurface vicinity of indentation contact zone

Abstract

Deformation regularities of crystals, films and coated systems assume ever greater importance in recent years. Particularly, it concerns the micro- and nanoindentation processes because of their large practical application. The microstructure of deformed zones under quasistatic nano-microindentation of some of coated systems (Cu/LiF, Cu/MgO, ITO/Si, SnO2/Si) was considered in the work to study the deformation specificity of coated systems as a whole, comparing their behaviour with this of the bulk crystals (LiF, MgO, Si) used as substrate. It was revealed plastic round pile-ups of material near indentations on both the bulk single crystals and coated systems.
