Abstract: | Abstract The concentration-concentration fluctuations in the long wavelength limit S cc(0) and the Warren-Cowley short range order parameters (SRO) α1 have been calculated for the Zn-Au liquid alloy at 1173 K by applying the Quasi Chemical Approximation (QCA). The results of the calculations show that Zn-Au liquid alloy manifest hetero-coordination throughout its whole concentration range. There exist evidence for the presence of two complexes Zn4AU3 and Zn4Au6. The Zn4Au3 complex which manifests dominance in the thermodynamic properties of the liquid alloy yielded a minimum short range order value of about αmin 1 ≈ ?0.26 while Zn4Au6 has its minimum as αmin 1 ≈ ?0.34. Studies from the S cc(0) indicate that these complexes are weak and hence cannot encourage glass formation in the liquid alloy. |
