What are the principles for using a Vickers hardness tester?

For all hardness testing methods, the basic principle is to observe the ability of an unknown material to resist plastic deformation.
The Vickers test is applicable to all metal materials and has a wide range of applications in hardness testing. In hardness testing, the unit of the hardness value is Vickers hardness (HV) or Diamond Pyramid Hardness (DPH). The indenter should have a specific geometric shape such that the produced indentation remains geometrically similar regardless of its size; furthermore, the indentation must have clearly defined boundary points for easy measurement. Additionally, the indenter must possess very high strength to resist its own deformation. A diamond indenter in the shape of a square-based pyramid can satisfy all of these requirements.
