| Abstract Scope |
Despite nanostructured and amorphous metals often demonstrating exceptional mechanical, chemical, and irradiation resistant properties, their poor thermal stability restricts their application to the research environment. In order to develop advanced nanostructured and amorphous metallic coatings for extreme environments, a rapid synthesis and characterization methodology must be employed to screen a wide compositional space to identify stability trends. In this study, 169 unique Fe-W coatings were synthesized via combinatorial magnetron co-sputtering and later annealed up to 750°C for 48 hours. Both as-sputtered and heat-treated coatings were characterized via high-throughput SEM, EDS, and XRD to identify composition and thickness-driven effects on amorphous content and thermal stability. Guided by high-throughput results, TEM was employed to investigate select films within the nanocrystalline, amorphous, and mixed regimes. Overall, by implementing a combinatorial and high-throughput approach, stability maps can be rapidly generated for amorphous-nanocrystalline systems to identify the effects of synthesis parameters and film characteristics. |
