Abstract Scope |
The optimization of FeCrAl alloys for use as an accident tolerant fuel cladding requires an understanding of how the complex microstructure dictates the mechanical response in service. In the presented work, we have analyzed the response at the microstructural scale using in-situ the Electron Backscattered Diffraction (EBSD) technique within a scanning electron microscope (SEM) equipped with a tensile stage. The applied load and crosshead displacement were correlated with locally measured strains and microstructural features within the material. Accumulation of the strain in the materials take place on the expense on the local mis-orientation change within the grains and along the grain boundaries. These identifications were carried out for different prior microstructural features that were developed via wrought, warm-rolled, welded, and neutron irradiated FeCrAl variants. |
