Registered Microhardness

Compared with conventional hardness testing methods, which allow solely the determination of a hardness value, the use of registering electronic measurement equipment (instrumentation) permit the recording of the total load–indentation depth–behaviour of the indentation process, whereby a significantly higher information content about the material behaviour is achieved (e.g. stress relaxation, creep, plastic and elastic parts of the total energy…). Due to the relatively low test forces used in the microhardness test, well-targeted investigations of the properties of shallow structures, structural components and coatings are possible.

Specimen Preparation

  • Specimen requirements: smooth, flat, plane-parallel, minimum thickness (10 times of the indentation depth)
  • Extraction from component parts
  • Embedding, whetting and polishing as needed   

Testing Conditions

  • Registered microhardness tester FISCHERSCOPE® H100c
  • Testing load up to 1 N
  • Vickers indenter
  • Individually programmable cycles of loading and unloading relating to control type (force- and indentation depth-controlled), preload and testing load, loading time and loading rates, etc.
