Nanoindentation has long been established as an effective method for determining the hardness and Young¿s modulus of metals in small-scale. The conventional high-temperature method permits the analysis of the material at elevated temperatures. Nevertheless, the possible modifications of the material that may occur prior to reaching the specified temperature cannot be quantified using this approach. The objective of the high temperature scanning indentation method is to address this shortcoming. The innovative approach permits the indentation of the material across the entire temperature spectrum, enabling the observation of phase transitions, grain growth, and other processes over an extensive temperature profile. This thesis presents a comparative analysis of the results obtained using the high-temperature scanning-indentation method on cobalt and those obtained using the conventional high-temperature-method. Furthermore, this study presents a comparative analysis of the advantages and disadvantages inherent to each method. In addition to the heat-treated state of Cobalt, which has already been analysed using the conventional method, a further state is investigated in this thesis. The second condition is distinguished by an ultrafine-grained microstructure. Prior to the implementation of the high-temperature scanning-indentation method, a comprehensive basic characterisation of both states is conducted with the assistance of a range of measurement systems.
