Abstract
Reduced activation ferritic Fe-14Â wt%Cr and Fe-14Â wt%Cr-0.3Â wt%Y2O3 alloys were produced by mechanical alloying and hot isostatic pressing followed by forging and heat treating. The alloy containing Y2O3 developed a submicron-grained structure with homogeneous dispersion of oxide nanoparticles that enhanced the tensile properties in comparison to the Y2O3 free alloy. Strengthening induced by the Y2O3 dispersion appears to be effective up to 873Â K, at least. A uniform distribution of Cr-rich precipitates, stable upon a heat treatment at 1123Â K for 2Â h, was also found in both alloys.
