Abstract
The physicochemical properties of nanosized binary alloys are investigated with respect to the effects of size, dimensionality, and composition using a nanothermodynamics model. The results indicate that the cohesive energy, melting temperatures of solid solution and eutectic alloys, Debye temperature, and order–disorder transition temperature decrease with decreasing material size for isolated nanoalloys, which is attributed to the severe bond dangling associated with increased surface/volume ratio. The model predictions are consistent with available test data and other theoretical results. This study has provided new insights into the basic understanding of the physicochemical properties in nanoalloys and also their potential applications in nanodevices.
