High entropy alloys (HEAs) are materials that contain more than four constituent elements at nearly equal concentrations; a feature that yields enhanced structural stability and performance superior to that of contemporary engineering alloys. Yet, the unique features of HEAs can only be harnessed to their full extent if the positions of constituent atoms are tuned with atomic to nanoscale precision. This is currently not possible, and our project seeks to address this challenge by combining cutting edge experiments with advanced computer simulations. The knowledge generated from the project will provide the scientific foundation for unlocking the full potential of HEAs for use in extreme conditions, including high mechanical and thermal loads, corrosive environments, and high radiation.
