The occurrence of the regions with different compositions of particular el ents in refractory high entropy alloys can be rationalized using the binary phase diagrams. The composition ra ge and the t mp rature interval relat d to the solidification a d the existence of solid solution above the occurrence of hexagonal phase are used to evaluate the efficiency for the element separation. © 201 9 The Authors.

The occurrence of the regions with different compositions of particular elements in refractory high entropy alloys can be rationalized using the binary phase diagrams. The composition range and the temperature interval related to the solidification and the existence of solid solution above the occurrence of hexagonal phase are used to evaluate the efficiency for the element separation.
