Abstract

An extension of the classic thermodynamic theory to nanometer scale has generated a new interdisciplinary theory - nanothermodynamics, which is an indispensable tool to investigate size-dependent physicochemical properties in nanocrystals. In this work, size-dependent Debye temperature and eutectic temperature of nano-sized binary alloys were investigated based on a nanothermodynamic model. It is found that both the Debye and eutectic temperatures decrease with decreasing crystal size for binary alloys at the nanometer scale due to severe bond dangling associated with the increased surface/volume ratio. The calculated results are consistent with experimental data and may provide new insights into the fundamental understanding of thermal stability in nanoalloys.
