Oxide dispersion strengthened steels are considered as cladding materials for Sodium Fast Reactor. Due to the nano-precipitates incorporated within the microstructure, their mechanical properties are very high, especially under creep loading. Moreover, the ferritic-martensitic lattice gives ODS steels a remarkable swelling resistance under radiation. The manufacturing route of ferritic ODS steels is complex and induces a strong morphologic and crystallographic texture. The microstructure needs to be recrystallized but this recrystallization is often heterogeneous and difficult to control. In this framework, this investigation aims at achieving a better understanding of the recrystallization mechanisms in ODS steels that strongly rely both o...
