MICROHARDNESS TESTING USING KNOOPS AND VICKERS METHODS
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.
IMR's metallurgical analysis team performs microhardness testing for manufacturers and their suppliers to verify material properties. For more information on our capabilities, click here to request a quote, or click on the button below.
