This investigation was supported by the Spanish Ministry of Science and Innovation (project No ENE 2008-06403-C06-04 and Juan de la Cierva program), the Comunidad de Madrid through the program ESTRUMAT-CM (grant S0505/MAT/0077), and the European Commission through the European Fusion Development Agreement (contract No. 09-240), the IP3 FP6 ESTEEM project (contract No. 026019) and the Fusion Energy Materials Science (FEMaS) FP7 coordination action.
Reduced activation ferritic Fe─14 wt%Cr and Fe─14 wt%Cr─0.3 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 homogeneousReduced activation ferritic Fe─14 wt%Cr and Fe─14 wt%Cr─0.3 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 873 K, at least. A uniform distribution of Cr-rich precipitates, stable upon a heat treatment at 1123 K for 2 h, was also found in both alloys.[+][-]
