A low-temperature ageing and irradiation study on 14YWT Nanostructured Ferritic Alloys for nuclear fusion applications

Abstract:

14YWT Nanostructured Ferritic Alloys (NFAs) are candidate alloys for tokamak blanket applications. They differ from conventional steels as they contain dispersoids that are distributed across its matrix. These dispersoids pin dislocations and grain boundaries, and are responsible for the superior high temperature properties associated with these alloys. However, at ≤ 475C, Fe-Cr based alloys are susceptible to the formation of α' precipitates. Their presence i...
