Abstract Scope |
The Fe-Cr-Ni-Mn-Al multi-component alloy system was investigated in order to assess the alloys’ potential use in nuclear material applications. Three alloys were fabricated via Spark Plasma Sintering with the following compositions: Fe-Cr-Ni-Mn, Fe-Cr-Ni-Mn-3.53 wt%Al, and Fe-Cr-Ni-Mn-10.86 wt%Al. The microstructures of these alloys were investigated using transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS). The increase of Al content (although relatively small) was enough to induce a different microstructure with respect to precipitate formation, which will be discussed in this presentation. Moreover 1 MeV Kr ion irradiations were performed in-situ in a TEM on these alloys to assess their phase stability and resistance to radiation damage formation. Understanding the effects of additional alloying elements on microstructure will allow to tune the compositions for the improvement of multi-component alloy properties as it relates to nuclear applications and particularly radiation resistance and phase stability. |
