Comparison of three methods for determining Vickers hardness by instrumented indentation testing

Materials Testing, 2017
Abstract To address the problem of poor accuracy associated with using instrumented indentation tests to determine Vickers hardness, and the problem of selection of the most appropriate instrumented indentation approach, the finite element method was adopted to determine theoretical Vickers hardness values of different materials.

Development of an automatic Vickers hardness testing system using image processing technology

IEEE Transactions on Industrial Electronics, 1997
The mechanical characteristics of machines or machine parts depend on the properties of the materials from which they are made. Hardness is an especially important index for machine design. The Vickers hardness number of a test material is defined by the surface area of the indentation made in the surface of a test specimen by a diamond pyramid ...
