Experimentally quantifying the mechanical effects of radiation damage in reactor materials is necessary for the development and qualification of new materials for improved performance and safety. This can be achieved in a high-throughput fashion through a combination of ion beam irradiation and small scale mechanical testing in contrast to the high cost and laborious nature of bulk testing of reactor irradiated samples. The current work focuses on using high-throughput pyramidal and spherical nanoindentation protocols on unirradiated and proton irradiated (10 dpa at 360 °C) 304 stainless steels, ferritic-martensitic, and Oxide Dispersion Strengthened steels to quantify the mechanical effects of radiation damage in an environment similar to the operating environment. Measurements from Berkovich nanohardness, micropillar compression, spherical nanoindentation, and micro-tension measurements will be compared and contrasted for this class of materials.
