The asymptotic behavior of the minor element, Z, in a X-Y-Z ternary alloy associated with decomposition of the major element, Y, is classified into three groups according to the sign of the second derivative of the chemical free energy f_1 with respect to the concentration of Y, c_Y and the concentration of Z, c_Z: In the case of ∂^2f_1/∂c_Y∂c_Z > 0, the value of c_Z along the trajectory of the peak top of the Y decreases with time. When ∂^2f_1/∂c_Z∂c_Y < 0 at 0 ≤ t < ∞, peaks of c_Z formed at peak tops of Y. The amplitudes of these peaks increase with time. if ∂^2f_1/∂c_Y∂c_Z < 0 at 0 ≤ t < t_0 and ∂^2f_1/∂c_Y∂c_Z > 0 at t_0 < t < ∞, bifurcation of peaks occurs at the later stage.
