Abstract Scope Life extension of current nuclear reactors and development of advanced reactors require an improvement in irradiation tolerance of nuclear materials. Austenitic and ferritic-martenstic steels have important applications in current and advanced nuclear reactors, however, their irradiation tolerance and mechanical properties need to be improved. Bulk nanostructured metals possess dramatically higher strength than their conventional coarse-grained counterparts, and have significantly enhanced irradiation tolerance due to significant volume fraction of grain boundaries that serve as sinks or recombination centers for radiation-induced defects. In this study, austenitic and ferritic-martenstic steels were processed by equal-channel angular pressing (ECAP) and high-pressure torsion (HPT). The microstructure and mechanical behavior of the ECAP and HPT processed steels were carefully studied, and their thermal stability was also investigated. Advanced microstructural characterization techniques were utilized to investigate the microstructures and chemistry of the steels before irradiation. Neutron irradiation was designed to study irradiation behavior of the steels.
