Mutual solubility in nanosized Au-Ni system

Abstract

The results of experimental studies of the effect of size on the solid state mutual solubility in a binary Au (35 at. %)-Ni film system have been reported. Film systems were formed by successive condensation of the components from independent sources in a high vacuum. The formation of a solid solution was detected by ED while heating directly in the PEM-125K electron microscope. It has been found that the formation of a uniform solid solution in layered Au-Ni film system with total thickness of 23 nm takes place at425 °C. This value is substantially lower than appropriate for macroscopic systems one.
