摘要：

Miedema's semi-empirical 'macroscopic' atom model, by which estimates of the enthalpy of formation of binary alloys can be calculated, is extended in order to be able to estimate values for the formation enthalpy of anti-site and quadruple-defect disorder in C15 compounds. These values can be used to predict the type of disorder that is created in C15 compounds by heating or ballistic action. Ball milling experiments have been performed on some GdX2 C15 compounds. The results are reported and compared to the predictions obtained by the model. (C) 1998 Published by Elsevier Science Limited. All rights reserved.
