The Idea of Nanoindentation
In Nanoindentation, a sample is indented with a small diamond tip (tip radius some nm).
In situ Nanoindentation can give more information on the formation and propagation of mechanically induced dislocations and defects during the experiment.
The In Situ Nanoindenters are compact, robust, versatile and can be fitted to various kinds of microscopes such as Scanning Electron Microscopes (SEM), light microscopes, Synchrotron beamlines, and many more. The idea of nanoindentation arose from the realization that an indentation test is an excellent way to measure very small volumes of materials.
