ResumoA new method, based on second-order elasticity, has been developed to predict departures from Vegard's law in binary alloy systems in which the end members have similar outer-electronic structures. This method has been found to be successful in predicting the correct sign and order of magnitude of the deviation in 28 of 44 binary systems. It has also been compared with 7 techniques presented in the literature, and was found to be a significant improvement over the other techniques. The new approach described herein contributes to the understanding of departures from Vegard's law, and its general applicability to all systems has been noted.
