Summary: | Results of investigations of the structural state of the AlNiNbTiCo high-entropy alloy (HEA) obtained by mechanical synthesis of pure Al, Ti, Ni, Co, and Nb metals for 30, 40, and 50 min are presented. It is shown that the AlNiNbTiCo HEA belongs to stable structures near the melting temperature. By the method of inverse convex hulls (InveseHubWeb), the temperature interval of structure stability equal to ∆T = 1578–2935 K has been found, and the lattice is created by predicting the structures in the USPEX code. The amorphous AlNiNbTiCo HEA structural state is determined by the simple AlNiNbTiCo-3 cubic lattice. It is shown that the AlNiNbTiCo-3 lattice dominates in the AlNiNbTiCo HEA synthesized for 30, 40, and 50 min. |
