The strong attention on high entropy alloys prompts new examination of concepts from solid-solution hardening, to predictive alloy behavior. Similarly, the advent of high-throughput computation has provided a significant quantity of new alloy data. However, the exponential growth of the number of potential structures with the number of elements precludes a brute force examination of four- and five-component alloys. The focus of this talk is how computation and simulation of binary materials sheds insight into the behavior of high entropy alloys and others with a large number of nearly equiatomic components, with an eye toward the broader area of alloy design and discovery. Such work sheds insight into HEA stability, mechanical properties, and phase evolution in Al-containing HEAs.
