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 x e , at which, regardless of the supporting element, the lattice parameter a s.s. , or Debye temperature θ D s . s . have the fixed value. It was established that the deviation of the lattice parameter is Δ a s.s.  = (0,01–0,03) nm and the Debye temperature is Δ θ D s . s .  = (40–80) K.
