Hardness measurement is a fast method for determining the mechanical properties of parts due to the quickness of the test and the need for light preparation. Also, the hardness value can be used to determine the macrostructure and microstructure of the parts. This test method can be done without destroying the sample. Hardness measurement is used for wide categories of metals and non-metals due to the variety of scales and applied forces. Also, hardness measurement is a reference method for determining the accuracy of heat treatment applied on parts.
