摘要：

The changes in Gibbs energy were evaluated for the atomic configurations resulting after different diffusional processes, in order to detect the mechanisms that are responsible for stabilisation and rubber-like behaviour. The energies and the proposed atom interchanges were compared with the experimental evidence. The influence of the changes in short- and long-range order was evaluated in the binary and ternary Cu-based alloys. (C) 2003 Elsevier Science B.V. All rights reserved.
