ABSTRACTA tight-binding-bond approach to interatomic forces in disordered transition metal-Aluminium alloys is presented. The bond-order is calculated on a Bethe lattice reference system, well adapted to topologically disordered alloy. It is shown that the bond-order depends strongly on the strength of the pd hybridization in the AB alloy, leading to non additive potentials with a strong preference for the formation of pair of unlike atoms and short bond-distances in the A-B pairs. This is illustrated by studying the structural properties of liquid Al80Ni20 and Al80Mn20 alloys using molecular dynamics simulations and by comparing our results with the available experimental ones.
