Challenges in design and development of high entropy alloys: A thermodynamic and kinetic perspective
Publikováno v:
Scripta Materialia. 188:37-43
High entropy alloys (HEAs) have brought a renewed interest to thermodynamics and kinetics. Proper understanding and treatment of relevant quantities are important for the effective theoretical design framework. Since the ideal mixing treatment is use

An experimental-ab initio approach is applied to investigate solute diffusion in hexagonal high-entropy alloys. The radioisotope 57Co is selected to probe the diffusion behaviour in a series of HCP alloys, from equiatomic binary (HfZr) and ternary (H
