Thermodynamic description of the Al–Sb–Y system

The phase equilibria of the Sb–Y and Al–Sb–Y systems were analyzed and a complete thermodynamic description of this ternary system was obtained. The thermodynamic descriptions of the other two binary systems were taken from the literature. Most of the binary intermetallic phases, except Sb3Y5, were assumed to have no ternary solubility. Based on the experimental data, the calculated phase equilibria were in good agreement with the experimental data.
