Indentation creep

The aim of the project is the development of new loading protocols for the investigation of thermally activated processes, such as creep or brittle-to-ductile transitions, of different high-temperature materials at temperatures of up to 1100°C. In particular, the further development of a high-temperature creep device, as well as the newly developed Constant Contact Pressure (CCP) indentation creep method, is the focus of the second funding period of the DFG-funded project. (DFG project no. 326946902) In particular, the CCP method has to be adapted for non-self-similar indenter geometries.

A particular challenge for the local determination of mechanical properties by means of nanoindentation is the wear of the indenter tips. Therefore, new potentially suitable indenter materials have to be found and applied as tip material, enabling stable long-term operation with low tip wear at high temperatures.
