The deformability and superhardening in epitaxially grown W/NbN nanolayers under shallow and deep nanoindentation, were discussed. To investigate the individual interface effect, shallow nanoindentations were made to a depth equal to the individual layer thickness of the epitaxially grown W/NbN nanolayers. It was shown that the increase in hardness is related to the nature of the interface between the layers in the superlattice materials.
