The concentration dependences of melting temperature , Debye temperature and lattice parameter as.s. for massive high-entropy alloys based on Fe, Ni, Co, Cu and Al were analyzed within the concept of additivity of physical values of high-entropy alloys. 4- and 5-component alloys were considered in the form of single-phase solid solutions. It was established that can vary within 150 K, that is, is insensitive to changes in the concentration of individual atoms. It is even less sensitive to concentration since the maximum value is ≅80 K. The lattice parameters change in accordance with Vegard's rule.
