On extracting mechanical properties from nanoindentation at temperatures up to 1000 °C

The creep behaviour has been investigated via the nanoindentation hold segments. Above 700 °C, the observed creep exponents match the temperature-dependence of literature values in CMSX-4. In Amdry-386, nanoindentation produces creep exponents very close to literature data, implying high-temperature nanoindentation may be powerful in characterising these coatings and providing inputs for material, model and process optimisations.
