Oxide Dispersion Strengthened (ODS) steels with a Fe-Cr matrix are of great interest in the development of generation IV fission nuclear power plants as a fuel cladding material. These materials, elaborated by powder metallurgy, include a high density of Y-Ti-O oxide precipitates of a few nm, providing the main contribution to the ODS steels strength. During the fabrication process, powders of Fe-Cr steel, Y2O3 and TiH2 are milled together to obtain a super-saturated solution of Y, Ti and O, otherwise insoluble in Fe. The obtained powder is subsequently processed by Hot Extrusion or Hot Isostatic Pressing around 1100℃. This induces the precipitation of Y-Ti-O and leads to a fully dense steel with finely dispersed nano-oxides in high density...
