Optimization of the alloy composi- tion based on the microstructure, oxidation behavior, tensile properties and irradiation resistance led to the selection of an ODS Fe-10/12Cr- 6Al-0.3Zr+0.3Y2O3 alloy (named CrAZY).The project is currently focusing on the fabrication and char- acterization of 500um thick seamless ODS CrAZY tubes. ODS tube fabrica- tion typically requires the fabrication of a master tube and then a succes- sion of pilgering and annealing steps to decrease the tube thickness from several millimeters to 0.5mm. The process needs to be tailored based on the alloy microstructure and properties and may lead to anisotropic mechanical behavior for the final tube. Specific ring and tube specimens were designed at Oak Ridge National Laboratory (ORNL) to measure the tube room tempera- ture tensile properties along the tube Figure 2: Electron Backscatter Diffraction (EBSD) grain map of the CrAZY tube, a) Perpendicular to the tube length and b) along the tube length showing elongated grains and sub-grains along the pilgering direction.
