Vickers Hardness Scale
The Vickers hardness scale is one way in which the hardness of a material is represented numerically. Hardness is the resistance of a material to indentation and is measured by the permanent depth of an indentation that has occurred. The Vickers hardness scale value is determined by what is sometimes called a microhardness test and is particularly well-suited for small or thin materials. The indentation resulting from the application of a light force is measured using a microscope and used to determine the Vickers hardness scale measurement.
