Abstract

We report the results of an orbital free ab initio molecular dynamics simulation of the structure and some dynamic properties of liquid Al3Li at T=1000K, using 1000 particles and averaging over a total of 21ps. The structure factors show a clear prepeak at a very small wavenumber, ≈0.5Å−1, suggesting the presence of large clusters in the alloy. The analysis of the distribution of coordination numbers suggests the presence of two types of Li atoms, giving some support to a model of clusters swimming on a ‘normal’ alloy, proposed in the literature for Tl-rich liquid Cs–Tl alloys.
