Vickers Hardness of Diamond and cBN Single Crystals: AFM Approach

Crystals, 2017
Atomic force microscopy in different operation modes (topography, derivative topography, and phase contrast) was used to obtain 3D images of Vickers indents on the surface of diamond and cBN single crystals with high spatial resolution.

Conventional Vickers and true instrumented indentation hardness determined by instrumented indentation tests [PDF]

Journal of Materials Research, 2010
We evaluate Vickers hardness and true instrumented indentation test (IIT) hardness of 24 metals over a wide range of mechanical properties using just IIT parameters by taking into account the real contact morphology beneath the Vickers indenter. Correlating the conventional Vickers hardness, indentation contact morphology, and IIT parameters for the 24
