What Is Vickers Microhardness?

The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials.

What is the purpose of Vickers hardness test?

In most cases, the Vickers hardness test is used to determine hardness in materials in the micro hardness test load range. However, the Knoop hardness test is often used when hardness testing thin layers, such as coatings, or to overcome the problem of cracking in brittle materials.

What does Vickers hardness measure?

Vickers hardness, a measure of the hardness of a material, calculated from the size of an impression produced under load by a pyramid-shaped diamond indenter.
