NSUF 16-700: Analysis of differential damage in binary carbide hybrids undergoing radiation damage

Through the novel use of high resolution post irradiation analysis, coupled with samples irradiated using in-situ irradiation with online monitoring of damage, provides for enhanced understanding of the effects of damage, and the effects from gas bubble formation. Applying this methodology to a range of binary carbide hybrids, allows for inter, and for that matter intra, granular effects of damage/bubble formation to be examined. The systems studied in this process are a mix of SiC-TiC across a series of grain sizes, prepared using spark plasma synthesis based techniques. The results obtained here will provide information that is not easily obtainable using with in-situ irradiation, or post examination of bulk irradiated samples, on their own as it now provides a unique ability to monitor the damage as it builds within the sample. This ability provides for the sample to be examines post irradiation using high resolution TEM, coupled with APT, the proposal here provides for sample preparation and analysis using FIB/TEM at ORNL with APT being undertaken in conjunction with research collaborators. The results from this proposal will greatly improve the understanding of inter/intra granular effects of such hybrids and will be used to develop the next generation of materials in this area.
