Hardness testing

Hardness testing

Hardness tests are used to determine the resistance of a material against permanent deformation. Several such tests exist whereby the material under examination is indented until a lasting impression is formed. The basic principle is to observe the material's ability to resist plastic deformation by a loaded standardized penetrating body (pyramidal indenter for Vickers tests, ball indenter for Brinell and Rockwell tests).

Application fields : Material conformity, weld analysis, qualification of welding procedures, brittle structures, wear ...

 

Micro-hardness testing

The term "micro-hardness" is employed to describe the hardness testing of materials with low applied loads. This testing is used for the characterization of some material components, studies of coatings and tests on very small workpieces.
