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.

Les alliages à haute entropie (heas) sont la nouvelle classe de matériaux avec une microstructure et des propriétés très uniques. Ils contiennent quatre composants ou plus en pourcentage atomique égal ou proche. L’entropie configurationnelle élevée associée au mélange de plusieurs éléments inhibe la formation de phases intermétalliques fragiles en faveur de solutions solides aléatoires multicomposantes. En raison du nombre énorme de combinaisons de composants et de leurs concentrations, l’étude expérimentale de toutes les combinaisons est impossible. Ainsi, la stabilité de phase et les propriétés des héas ne sont pas encore très bien connues et il n’existe pas de théorie unifiée existante pour couvrir les aspects atomistiques et thermodynamiques des héas. Les simulations réalisées dans le cadre de ce projet permettront non seulement d’améliorer la compréhension de cette nouvelle classe de matériaux, mais aussi de concevoir de nouvelles compositions d’alliages avec des propriétés uniques pour des applications industrielles potentielles.
