The evolution of the structure and electrical-transport properties of high-entropy CrMnFeCoNi (A) and CrMnFeCoNi$_{2}$Cu (B) alloys under heat treatment is investigated. As shown, the alloy A contains of a single f.c.c. phase. The alloy B consists of two phases: base one, with the lattice parameter close to that of the alloy A, and additional f.c.c. phase. The additional phase is revealed clearly after annealing. As found, the parameters of electrical resistance of the alloy A are thermally stable, while some rearrangements within the additional phase of the alloy B result in a small influence on the thermal stability of its electrical-transport properties.

Key words: structure, electrical resistance, thermal stability, high-enthropy alloy.
