Vickers Hardness Test

Vickers Hardness Test

A hard metal point, called an indenter, is pressed into the surface of the material being tested with a measured force. Softer materials will produce a

deeper indentation. The test piece is considerably thicker than the indentation. The test material is placed on a table, which can be adjusted for height.

The Vickers hardness test uses a diamond, square-based pyramid indenter. It has a point angle of 136 °.

Advantages:

Vickers has a wide range of hardness values. Its scale ranges from 114 to 545. It overcomes the limitations associated with Brinell testing. Excellent for components with high hardness, also suitable for testing some finished components due to the small indentation it leaves.

The hardness value for a Vickers hardness test is converted from the length of the diagonal produced by the indenter.
