Vickers Hardness Test Method

Vickers Hardness Test Method. The vickers hardness number is also determined by the load over the surface area of the indentation as like brinell number. In the vickers hardness test, an optical method, the size of indentation (the diagonals) left by the indenter is measured.

The vickers hardness test or the 136 degree diamond pyramid hardness test is a microindentation method.the indenter produces a square indentation, the diagonals of which are measured. The test forces used in the macro range in the vickers method are mostly substantially smaller than those used in the brinell method. Vickers hardness number (vhn) can be found directly from the vickers hardness testing machine.

The indenter used in the vickers test method is a diamond pyramid with a square base, whose opposite sides meet at the apex at an angle of α = 136°. Here the vicker’s hardness number will determine the hardness of the materials.

The preferred choice for the macro range is 49, 98, 196, 294, 490 or 980 n, with 294 n being used most frequently for testing in practice. The vickers hardness test is a static hardness test method, used for both macro and microhardness testing.
