| Abstract Scope |
Nanocrystalline materials have been proposed as promising candidates for advanced nuclear applications due to their high grain boundary density. Indeed, grain boundaries are known as efficient sinks for irradiation-induced defects and numerous studies have presented evidence of enhanced radiation damage tolerance in various systems. However, very few studied the effect of grain size on radiation-induced segregation. This presentation will report on radiation-induced segregation after ion irradiation in Fe-based alloys. A range of grain sizes was fabricated through high pressure torsion with subsequent anneal and compared to conventionally processed samples. To isolate the irradiation effect, thermal segregation was also studied and will be reported. |
