Idaho State University, in collaboration with Idaho National Laboratory, proposes to enhance the fundamental understanding of irradiation effects in ultrafine-grained or nanocrystalline steels produced by equal-channel angular pressing (ECAP) or high-pressure torsion (HPT), and to assess the potential application of ECAP and HPT in fabricating materials for application in current and advanced reactors. The project will involve neutron irradiation and post-irradiation examination of bulk nanostructured austentic and ferritic/martensitic (F/M) steels that are anticipated to have enhanced irradiation tolerance and are produce by innovation and low-cost manufacturing techniques ECAP and HPT.
