| Abstract Scope |
This presentation will highlight the effect of changing elemental compositions on the crystallography of compositionally complex alloys (CCAs). Magnetron sputtering will be employed to synthesize a combination of elements with varied crystal structures. This technique allows for easily tunable conditions such as operating power, working pressure, and working gas, among others, that influence the composition of each of the alloying elements present. Preliminary results indicate that there is a transition from a BCC to a FCC crystallographic structure when altering the composition of each of the alloying elements. The goal of the project is to see how varying the composition of these elements influences the overall crystallographic structure of the sputtered CCA, and to explore the non-equiatomic composition space of the sputtered CCA using high-throughput techniques. |
