ODS FeCrAl alloys are promising candidates for accident-tolerant fuel cladding due to their excellent oxidation resistance in steam at very high temperature, great mechanical properties up to ~800șC, and limited radiation-induced embrittlement at low temperature. Several ODS alloys were fabricated by extrusion of Fe-10-15Cr-5-6Al+Y2O3 ball milled powders. The impact of ball milling duration, extrusion temperature, and minor element additions on the mechanical and oxidation performance of the alloys were evaluated. The results led to the selection of an Fe-10Cr-6Al-0.3Zr + 0.3 Y2O3 ODS FeCrAl alloy for tube fabrication. The master tube was obtained by gun drilling a rod extruded at 1100șC. Several cold pilgering and annealing steps were required to produce a ~500um thick tube. The impact of cold pilgering/rolling and subsequent high temperature annealing on the alloy microstructure and mechanical properties will be discussed.
