Abstract Scope |
Next-generation energy technologies require advanced materials with enhanced irradiation damage resistance and thermal stability. Selected nanostructured metals incorporating amorphous phases have shown promising irradiation tolerant properties; although, significant excess free energy typically associated with these metastable phases serves as a driving force for thermally induced microstructural evolution. Therefore, understanding the formation of brittle intermetallics is of significant importance for designing advanced amorphous alloys for extreme environments. This work utilizes combinatorial and high-throughput (CHT) synthesis and characterization techniques to screen a large design space within Fe-based alloy systems, including solid-state amorphization. By depositing co-sputtered films with compositional gradients, hundreds of unique samples were generated per experiment. All compositions are heat-treated and characterized via ex-situ SEM, EDX, XRD, and nanoindentation to determine morphological, structural, and mechanical behavior, thus highlighting the ability to tailor amorphous stability and devitrification within nanostructured Fe-based alloys. |
