Vickers hardness testing is a multifaceted testing method that can be used for both micro and macro hardness testing. Vickers hardness test was developed by George E. Sandland and Robert L. Smith in 1921 as an alternative to the Brinell method for measuring material hardness.
The ability of any certain object or substance to resist indentation when a force is applied to it is known as hardness. An object’s hardness should be classified as a feature or a characteristic rather than one of its properties and the hardness is generally measured by calculating the permanent area of the indentation caused by a fixed load.
The hardness test was developed at Vickers Limited, and it serves as the alternative test to another hardness test called Brinell hardness method which is used to determine the ability of a material to resist indentation. Vickers Hardness is also known as micro hardness testing.
Hardness is the property of any material to resist deformations to its shape when it is subjected to an external force. Hardness testing is important for technical and engineering applications as it helps to determine the hardness and tensile strength of materials.
