Abstract

A microscopic theory of order-disorder phase transitions in binary alloys is oresented. The internal energy of the system is calculated within the tight-binding Hamiltonian and long- and short-range order effects are included by solving the equations of motion for the Green's functions in the Be the lattice approximation. Results are presented for the electronic local density of states and for various values of the long- and short-range order parameters.
