| Abstract Scope |
The exceptional performance and high tunability of high-entropy materials has led to significant research into the possibility of using such materials for energy applications. However, optimizing high-entropy compositions for tailored applications is challenging due to the vastness of the high-entropy design space. There is a particularly pressing need for rapid, quantitative property assessments to identify promising high-entropy candidates, down-select compositions for further study, and provide experimental inputs to facilitate model development. In this talk, I will describe how resonant ultrasound spectroscopy (RUS) measurements of elastic constants and ultrasonic attenuation are a prime candidate to address this need and how such measurements can serve as a benchmark for materials design, model development, and model validation. Comparisons between theoretical predictions and temperature-dependent RUS measurements on a range of refractory high-entropy alloys will be presented to exemplify this approach. |
