Abstract
We present microscopic calculations of the chemical short-range order in amorphous and liquid alloys of two transition metals. Our approach is based on a model one-band tight-binding Hamiltonian and a thermodynamic variational technique founded on the Gibbs-Bogolyubov inequality and a hard-sphere Yukawa fluid as a reference system. We calculate the Bhatia-Thornton partial structure factors of Nix Ti1−x and Nix Zr1−x alloys and find good agreement with experiment.
