Meeting on Thermodynamics of alloys (TOFA) location:Cracow, Poland date:22-27 June 2008
The CALPHAD (CALculation of PHAse Diagrams) method provides a powerful tool for the calculation of phase diagrams. It is based on thermodynamic databases gathering information on the relative stabilities of pure substances and mixing properties of alloys. We have added a size dependent contribution to an existing CALPHAD description of the Au-Ge bulk system. The parameters are optimized using composition and temperature dependent Surface energies calculated according to the Butler model. The effect of particle size on the phase diagram is discussed for spherical nano-particles.
