The concentration dependence on the lattice parameter and the Debye temperature in four-six components of solid solutions, including high-entropy solid solutions based on Fe, Co, Ni, Cu, Cr, Al, and Ti, is analyzed. During the calculations, each of the four-six metals was alternately used as doped, the atoms fraction concentration of which, as would be expected in the case of an equiatomic alloy, varied within x = 0–0,30. For each four-six component system there is such a value of the equilibrium concentration xe, at which, regardless of the supporting element, the lattice parameter as.s., or Debye temperature 
have the fixed value. It was established that the deviation of the lattice parameter is Δas.s. = (0,01–0,03) nm and the Debye temperature is 
= (40–80) K.
