The search of high entropy alloys (HEAs) has become the focus of many researchers due to the promising properties of these alloys and their potential applications in various fields. Different from the traditional alloys, design of HEAs involves the use of multiple principal components. Since huge multi-dimensional composition space needs to be explored, finding the right HEA compositions becomes even more challenging. Traditional trial-and-error approach is no longer feasible due to the tremendous amount of experimental work. In this presentation, we will demonstrate that the CALPHAD method can be used as an effective approach in aiding HEA design. High-throughput calculation can be performed in the multi-dimensional composition spaces to accelerate the search of potential HEAs with user-defined optimal properties. We will also demonstrate that phase-stability diagrams coupled with density contours in the composition-temperature space provides helpful guidelines for the design of low-density HEAs with desirable combinations of properties.
