The concept of high-entropy alloys (HEAs) opens up a new idea for developing advanced lightweight alloys for extreme-environment applications. Here, a series of lightweight HEAs are designed by the CALPHAD-based high-throughput computational method, targeting the high-temperature and cost-effective applications. These new alloys were investigated from the perspectives of structure, property, and deformation behavior, by the state-of-the-art neutron scattering and advanced microscopy. It is found that the local structure plays a critical role in controlling the morphologies of the constituent phases and the properties of these new lightweight HEAs. The present study provides helpful insights into tuning the properties of lightweight HEAs by tailoring their local structures.
