High Entropy Alloys (HEA) are a new class of metallic alloys with 5 or more principal elements, with the concentration of 5% to 35% each one. Due to their unusual design, these alloys often exhibit special properties. The combination of such properties as low density, high strength, and corrosion and temperature resistance makes possible many potential applications
of HEAs in aviation, engineering, orthopedics (bone implants), etc. The aim of our work is to study how a particular atomic configuration, or the microstructure of HEAs, affects their electronic and elastic properties.
We use an evolutionary algorithm implemented in the USPEX code to predict the structure of the HEAs. This algorithm predicts the stable crystal
structure for a particular chemical composition using total ground state energy as a stability parameter. For calculations of the elastic properties, we use VASP code.
