Reassessment of the Ag–Cu phase diagram for nanosystems including particle size and shape effect

In order to extend the CALPHAD technique to nanosystems, the thermodynamic description involving the particle size and the shape factor was presented and employed in the calculation of the phase diagram of the Ag–Cu nanosystem.

► Defining the shape factor for the thermodynamic calculation. ► Definition the Gibbs free energy as a function of size and shape. ► Calculation of the phase diagram of the Ag–Cu nanosystem.
