| Abstract Scope |
Microstructure characterization and micro-mechanical testing and has been carried out on 14YWT nanostructured ferritic alloys processed under various thermo-mechanical paths (hot extrusion and hydrostatic extrusion with various annealing temperatures). These alloys are a leading candidate for fast nuclear reactors operating at high temperatures. Electron backscatter diffraction was used to identify the principle texture and microstructure components. Transmission electron microscopy was used to characterize the morphology, dislocation density, and oxide particles. Novel in-situ micro-pillar compression and micro-tensile testing in a scanning electron microscope at various temperatures (25, 300, 600°C) was used to determine the mechanical behavior and deformation mechanisms. Results will compare the properties with respect to the underlying microstructure and processing conditions, as well as be compared to previous macro-scale results on similarly processed on 14YWT. |
