• Thermodynamic Evaluation of Binary Alloy Phase Diagrams of Small Particle Systems

抄録

Binary phase diagrams of nano-particle alloy systems have been evaluated from the information on the Gibbs energy and the surface tension of bulk systems. As the size of a particle decreases, the melting point of pure component decreases and the liquid phase region is enlarged in binary phase diagrams, in other words, the liquidus temperature decreases. In addition, solid solutions in nano-particle systems have larger composition ranges than those in bulk alloys. It is found from the above evaluation that the size dependence of a particle on phase diagrams is remarkable when excess Gibbs energies have large positive values in solid and liquid phases.
