X-RAY STUDY OF ORDERING PROCESSES IN QUENCHED CU3AU

Abstract

The kinetics of ordering in Cu3Au were studied as a functio of quench temperature. These studies indicate that the rate of ordering is related to the temperature of quench, being more rapid the higher the temperture. A significant aspect of the results is the profil of the X-ray line used to observe the ordering process, its nonsymmetric shape indicating that the process did not proceed homogeneously. It is suggested that this might be a result of the high degree of disorder quenched in, which permitted the nuclei present to grow to unexpectedly large dimensions before encountering other domains. The suggested employment of the order-disorder process to mo itor th r al history is not restricted to Cu3Au, but would be as applicable to other alloys exhibiting order-disorder transformations.
