Comparison of Vickers Hardness Numbers VH and LVH in the Case of Alumina and Doped Sapphire

physica status solidi (a), 1986
The complex penetration phenomenon in Vickers hardness testing is separated into simpler contributions accessible to approximate calculation: the formation of an indentation pit with well-defined corners, and the elastic depression of both sample and indenter.

Correlation of the Mohs's scale of hardness with the Vickers's hardness numbers

Mineralogical Magazine and Journal of the Mineralogical Society, 1949
Mineralogists have long been accustomed to describe hardness with the aid of a scale devised by Friedrich Mohs, who lived from 1773 to 1839. The test is qualitative, each mineral in the scale being capable of scratching those that precede it, but the ten minerals have held their ground as a useful representative series with which it is now interesting ...
