The Vickers hardness test follows the same principle of the Brinell test—that is, an indenter of definite shape is pressed into the material to be tested, the load removed, the diagonals of the resulting indentation measured, and the hardness number calculated by dividing the load by the surface area...

...). In the Brinell, Vickers, and Knoop tests, hardness value is the load supported by unit area of the indentation, expressed in kilograms per square millimeter (kgf/mm 2 ). In the Rockwell tests, the depth of indentation at a prescribed load is determined and converted to a hardness number (without measurement...
