Study of the Kinetics of Ordering in the Alloy AuCu

Abstract
Ordering in the alloy AuCu was studied by measurements of the electrical resistivity as a function of time and temperature of ordering for samples disordered at various temperatures above the critical point. It has been established experimentally that the disordering temperature has a profound affect upon the rate of ordering. The higher the disordering temperature the faster is the rate of subsequent ordering. The dependence of the rate of ordering on the ordering temperature seems to indicate that the transformation is nucleated even at very low temperatures. The appearance of a twin‐like structure during the disorder‐to‐order transformation has also been studied as a function of the previously mentioned variables.
