Order-Disorder Kinetics of Cu₃Au Studied by X-Ray Diffraction

Abstract

The ordering kinetics of the order-disorder phase transition in Cu₃Au has been investigated by X-ray diffraction. The time dependence of the (1 1 0) superlattice peak profile was measured at various temperatures. The data were analyzed on the basis of models for time developments of stable and unstable states. The results of the analysis revealed the features associated with the three characteristic temperatures, T_instability, T_c and T_classical.
