Concentration dependent structural parameters of liquid Al-Fe alloys

Square well potential is perturbed over Lebowtiz solution of hard sphere mixtures to determine direct correlation function,C(0)ij(r) in repulsive and attractive regions under Mean Spherical Model Approximation [1]. Obtained direct correlation functions were employed to derive partial structure factors and then total structure factor, S(k) in liquid Al-Fe alloy at different atomic percent of Al. Fourier transform of partial and total structure factors gives partial and total radial distribution functions, g(r) from which partial and total coordination numbers and the partial nearest-neighbor distances were computed.
