Principle and Applications of the Vickers Method

WebThe Vickers hardness test is a static hardness test method, used for both macro and microhardness testing. It is an optical method of testing where the size of the indentation left by the indenter is measured to determine the hardness value of a test specimen. Fig 1: Victor's Apparatus.
