Microhardness Testing
Microhardness testing utilizing the Vickers method utilizes a diamond indenter to make an indentation within a series of light load specifications (ASTM E-384) . The measurements are converted into a hardness value, which is useful for testing a wide range of materials.
The Knoop microhardness test measures mechanical hardness, and is used mostly for very brittle materials or thin sheets, where only a small indentation may be made for testing purposes. This testing is especially useful for alloy steels and irons or where testing for near surface hardness is needed.
