| Abstract Scope |
The use of novel technologies is vital to develop structural materials for the next generation nuclear reactors. In this study, a recently developed process called Shear Assisted Processing and Extrusion (ShAPE) was used to fabricate tubes from commercial oxide dispersion strengthened (ODS) FeCrAl (PM2000) alloy. ODS FeCrAl alloy was used here as it is known to have good oxidation and creep resistance at higher temperatures relevant to next generation nuclear reactors. The ShAPE process will be researched with respect to its processing parameters based on the characterization conducted on the samples of the extruded tubing. Preliminary data showed the presence of secondary (Al, Y)-Oxide phase in both base metal PM2000 and ShAPE samples, while some microstructural changes (e.g., grain size and texture) in the two materials were also observed. These observations together with the microhardness data of the samples will be discussed in this presentation. |
