Ag-cu phase diagram. By applying the obtained results and the critically evaluated literature data, we have developed a thermodynamic database. The self-developed database was combined with the latest pure substances database of the FactSage software package to model the phase diagram of the Ag 2 S-Cu 2 S system. Additionally, some compositions represent key regions of the Cu-Ag phase diagram, shown in Figure 9. For example the 30 wt% Cu - 70 wt% Ag alloy is very close to the eutectic composition (28.1 wt%... The phase diagrams of Ag-Cu nanoalloys were thermodynamically re-investigated. • A self-consistent thermodynamic data set including the size effect was obtained. • Four Ag-Cu nano phase diagrams were constructed and compared with experimental data. • The calculated Ag-Cu nano phase diagrams agreed well with experimental data. Abstract This phase diagram consists of two points, two lines and three areas. The two points of the two pure metals A & B. The upper line, obtained by connecting the points showing the beginning of solidification is called liquidius line, and the lower line, determined by connecting the points showing the end of solidification is called the solidus line.
