摘要
In this paper, the Regular Solution Model (RSM) and the Cluster/Site Approximation (CSA) were used to study the unmixing as a function of the thickness of the Co/Cu metal layers. The results show that decreases in the thickness of the layers leads to a lowering of the demixing critical temperature. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
