Abstract

Reducing the dimensions of material particles down to nanoscale, can affect the particle properties such as its melting point and equilibrium phase diagram. In this study, a program was developed by MATLAB based on the thermodynamics of surface. The program was used for plotting phase diagrams of nanosystems and comparing it with the bulk ones. According to this study, it was concluded that reducing the particle size to nanoscale leads to lower solidus and liquidus temperatures in the equilibrium phase diagram. Furthermore, reaching to nanoscales decreases the solid solubility regions.
