High entropy alloys (HEAs) are the new class of materials with a very unique microstructure and properties. They contain four or more components in equal or near equal atomic percent. The high configurational entropy associated to mixing several elements inhibit the formation of brittle intermetallic phases in favour of multicomponent random solid solutions. Due to the enormous number of combinations of components and their concentrations, the experimental investigation of all combinations is impossible. Thus phase stability and properties of HEAs are still not known very well and there is no existing unified theory to cover the atomistic and thermodynamic aspects of HEAs. The simulations performed within this project will not only improve the understanding of that new class of materials but they will enable the design of novel alloy compositions with unique properties for potential industrial applications.
