Abstract

Highly concentrated alloys, also known as high entropy alloys, are multicomponent alloys (with more than four components) in which none can be taken as predominant. The project aims at investigating the thermodynamics of the V-Nb-Ta-Mo-Al and V-Nb-Ta-W-Al systems and to investigate the role of thermodynamics on the development of diffusion paths in these alloys, with a newly derived algorithm. The project also aims at renewing the resources of the Computational Materials Science Laboratory, with the acquisition of a multicore workstation (16 cores, 32 threads), two computers and one printer, and one dedicated software licence.
