- Abstract:
- The load and partial unload technique adds partial unload processes to the load curve. The mechanical properties like elastic modulus can be determined for each of these unload curves. This allows for a faster depth dependent measurement of the characteristic quantities. If the elastic modulus of a material is known and not dependent of the depth, an indenter shape correction can be performed using this technique.
The results of such a correction are compared with those gained using a correction based on the Martens hardness of the material. The elastic modulus EIT as well as the Martens hardness HM are corrected with both methods.
The results of both approaches are comparable down to an indentation depth of 100 nm. A Fischerscope HM2000 was used to perform the measurements. - Keywords:
