Abstract

A study on alloy phase formation in nanometer-sized particles by insitu transmission-electron microscopy revealed that the phase equilibrium of these particles is significantly different from that of the corresponding bulk materials. A theoretical study was conducted based on thermodynamics modified so that Gibbs free energies for bulk materials available in the CALPHAD database were modified by taking into consideration factors affecting the phase equilibrium of nanometer-sized alloy particles. The study proved useful to evaluate the results obtained from experiments.
