The Karlsruhe Institu-te of Technology and the Materials Department of the University of Oxford are acknowledged for the overall use of their facilities. Four different ODS alloys were produced by mechanical al-loying of Fe13Cr1W0.3Ti + Fe2Y . The variation of the alu-minum content was done by the addition of FeAl3 interme-tallic powder. Examination of the microstructure for the materials was performed by focused ion beam. Minor differences were observed in the grain size distribution. The 0%Al-material has a smaller and bi-modal grain size distribution.*contact:Jan Hoffmanne-mail: j.hoffmann@kit.eduphone: +49 (0) 721 6082 3476Charpy impact tests Vickers hardnessThe tensile tests show a significant drop in strength for the Al-added alloys. All Al-ODS materials show similar behaviour in the range of the operating temperatures (600°C)Nearly no differences can be ob-served for the absorbed energy and DBTT values. The overall toughness of the 0%Al alloy is higher.Drop of 300HV30 in hardness for the Al-ODS materials.After consolidation via hot-isostatic pressing (1100°C, 100 MPa), the materials were hot-rolled  from 45 mm to 6 mm in 5 passes at 1100°C with reheating after each pass.Al-containing ferritic oxide dispersion strengthened alloysmechanical and microstructural propertiesConcepts for future generation nuclear reactors have demanding requirements for the structural materials. High neutron do-ses, elevated temperature combined with corrosive atmospheres form a harsh environment in which present materials cannot be used. Al-added ferrtic oxide-dispersion-strengthened (ODS-) materials have a high chance of meeting these requirements.Fe2YFeAl30%Alrolling direction
