Vickers Hardness Testing (HV) in laboratory
You wish to perform Vickers hardness (HV) testing on your materials
Definition of Vickers hardness (HV)
Vickers hardness (HV) testing, also known as Vickers microhardness testing, is an analytical method for assessing the hardness of materials. It is performed using a pyramid-shaped indenter to which a given force is applied for a given time. Vickers hardness is calculated from the size of the indentation left by the diamond.
What are the advantages and applications of this technique?
The main advantage of this analysis method is that it provides accurate results over a wide range of hardnesses. It is particularly useful for testing small parts or areas of fine microstructure.
This technique can be used to check the conformity of a material with technical specifications, to establish hardness filiations on a sample or to adjust the force of the impression applied.

FAQ
Vickers hardness is calculated by dividing the applied load by the surface area of the indentation. This area is determined from the average of the diagonals of the indentation left by the tip.
Vickers hardness measurement is suitable for a wide variety of materials, including metals, ceramics, plastics and composites, thanks to its extensive range of test forces.
The main difference lies in the indentor used: Vickers uses a pyramid-shaped diamond tip, while Brinell uses a steel or carbide ball. What's more, Vickers is better suited to thin materials or surface layers, thanks to its smaller footprint.
advantages include its versatility for different materials, its high accuracy, and its ability to test small areas, which is ideal for heterogeneous materials or small components sizes.
