Abstract
In this presentation, I will talk a few strategies for the fabrication of nanostructured HEAs. Those HEAs pillars exhibit high yield strengths and good ductility up to 1100 °C. I also demonstrate that such nanostructured HEA films show substantially enhanced stability for high-temperature, long-duration conditions. Nanostructured HEAs combining these properties represent a new class of materials in small-dimension devices potentially for high-stress and high-temperature applications. This study shows a new opportunity to study complex intermetallic phases in broad size and temperature regimes.
