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 ...
