Mr. Mike, it was my pleasure to collaborate with you in this study, which was initiated by your vision that it should be possible to answer the question about hardness change. 
In this study we assumed conical indenter. In the future we can consider the fully realistic scenario with spheroconical shaped diamond indenter. This means that the conical diamond indenter with 120° included angle is blending with a spherical tip of 200 microns radius.
