An oxide dispersion strengthened (ODS) steel with nominal composition Fe–14Cr–2W–0.4
Ti–0.3 Y 2 O 3 (wt%) has been manufactured by mechanical alloying of pre-alloyed powders
with nanosized Y 2 O 3, compacted by hot isostatic pressing and hot cross rolled. In order to
evaluate the long-term thermal resistance of the alloy, it has been subjected to 2000 h of
thermal aging at 873 K, which is a relevant temperature for nuclear reactor applications. A
thermodynamic equilibrium simulation indicates the precipitation of Laves phase under the …
