Micro vickers hardness calculation
WebHardness Test 2/5 the microscope is in millimeters. The larger diameter indentation corresponds to a softer material and lower Brinell number. VICKERS HARDNESS TEST The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees WebTo calculate the Micro Vickers hardness value of the material, it is imperative to understand the shape of the indenter and its unique impression type. The indenter forms a 136-degree angle between its faces with the pyramid-shaped diamond and a square base. Also, the diagonal length is seven times its indentation depth.
