Sample hardness value



The Vickers hardness test uses a diamond indenter with an angle of 136°. Due to its high hardness, the indenter can be used to indent almost any material, and the pyramid shape makes the indentation independent of the size of the indenter itself. Press into the surface of the sample under a certain test force and hold for a certain time, then remove the test force, measure the diagonal length of the square indentation on the surface of the material, and use the following formula to calculate F as load and S as indentation surface area , D is the average indentation diagonal length, g is the standard acceleration of gravity.
