Thermodynamic Modeling of the Ag–Al–In System

Thermodynamic models of liquid and ternary solid solutions in the Ag–Al–In system are constructed on the basis of available experimental information. These models and ones of other phases of this system known in the literature are used to determine the coordinates of invariant points of the Ag–Al–In system and a projection of its liquidus surface. Polythermal cross sections of the phase diagram of this system are calculated for compositions x_Al/x_In = 4.255, x_In/x_Al = 2.096, and x_Ag/x_In = 1.064, along with isothermal cross sections at 973 and 573 K.
