| Abstract Scope |
To improve the strength of vanadium-stabilized titanium alloys, we evaluate a novel method to fabricate and characterize compositionally graded sputter deposited foils thicker than 100um. Samples are heat treated to create homogenous structures, with composition variation from 3-25at%V. We utilize a combination of rapid quenching, cold rolling, and aging to induce omega phase precipitates across this composition range. Rapid analysis using XRD and XRF will be used to assess the formation of the omega phase, with indentation used to assess strength at each stage. The fraction of omega phase formed through each method and their contribution to strength will be evaluated throughout the composition range. Using this methodology, we aim to find a range of compositions and processing parameters that provide superior strength and stability, as well as accelerate materials discovery and development. |
