Abstract :
A new method of determination of the nearest-neighbor (1NN) coordination numbers for binary disordered alloys is proposed. The method is reduced to the solution of the system of linear algebraic equations for the partial coordination numbers. As input data we use 1NN partial interatomic distances obtained independently for each EXAFS spectrum in binary alloy and the Debye–Waller factors. Coordination numbers and interatomic distances for 75 and 80 at% Ni–Mn alloys in ordered and disordered states are presented.
