b'sample are being explored in order to increase the testing temperature.First ever high The measured elastic modulus andtemperature hardness versus temperature plotsnanoindentation was for the materials tested can be seensuccessfully performed in Figures 1 and 2. The values of theon high density elastic modulus measured with highaccident tolerant fuels. temperature NI agree well with the literature values measured through a variety of different techniques. In addition, the NI hardness values match well with literature values when there was data available for comparison. The future work forthe nanoindenter includes the measuring of Uranium Nitride (UN) at elevated temperature.2019|AFC ACCOMPLISHMENTS 67'
