Phase diagram and thermodynamic properties of Ag−Cu alloys
- 261 Downloads
Interactive laws of the components described by Gibbs energy functions of CC theory are different from each other, but each G-function can be used to draw the phase diagram of Ag−Cu system with almost the same accuracy. The partial molar properties of the components obtained from all these G-functions are identical. This shows the defects of thermodynamics of alloys. The thermodynamic properties of Ag−Cu alloys and their components have been calculated by the correct G-function which is chosen through a relative study of the energy, volume, atomic arrangement and electronic structure.
