Morphology of deformed zone of micro- and nanoindentation on crystals with different type of bond

Abstract

The comparison of microindentation (MI) and nanoindentation (NI) methods has been made. Differences between nanohardness (Hn) and microhardness(Hm) values were found. The deformation zone around these two types of indentations, the dislocation structure and the thin structure of indentation relief have their specific peculiarities, which were attributed to the scale effect and different deformation extent of material under MI and NI.
