Abstract
In this work, the structure of a CrMnFeCoNiCu high-entropy alloy (HEA) film deposited by magnetron evaporation on a steel substrate is studied. It is established that the phase content of the CrMnFeCoNiCu HEAs is determined by a superposition of contributions from equiatomic simple cubic lattices of the CrMnFeCoNiCu composition (Struct-26 and Struct-278) with space group P1. It is found that the contributions of the diffraction patterns from the reference lattices to the integral intensity are 0.66 and 0.29, respectively. For simple cubic lattices Struct-26 and Struct-278, the full structural information (the lattice parameters, coordinates of atoms, spatial groups, and occupancies) is derived. It is established that the CrMnFeCoNiCu HEA is a stable compound, which is confirmed by calculations of the mixing energy for the convex Hull model.
