High entropy alloys (HEAs) represent a vast, largely unexplored space of material systems with potentially revolutionary combinations of properties such as strength at high temperatures and resistance to oxidation and corrosion. Compositions in these material systems have the potential to surpass the operational temperature limits of current state of the art high temperature alloys. However, the search space for candidate alloys is huge, making efficiency and optimization of the exploratory process crucial. A multifaceted alloy discovery approach has been undertaken that couples advanced computational materials modeling, synthesis of combinatorial thin-film libraries, and high throughput experimentation to rapidly assess the properties of synthesized alloys and provide feedback loops to further refine future modeling and alloy synthesis. The present focus is on discovering lightweight high entropy alloys (LHEAs), a subset of HEAs with potentially unique properties. By including elements with low atomic numbers, we have discovered LHEAs exhibiting stable, single phase domains.
