The thermodynamic properties of Al-Ce melts

Abstract

Thermodynamic modeling of Al-Ce melts was performed at a total pressure p = 10(5) Pa in an argon atmosphere over the temperature and concentration ranges 1773-2373 K and 0 <= x(Ce) <= 1, respectively, corresponding to the liquid-phase region of the phase diagram of the system. The concentration and temperature dependences of the thermodynamic characteristics of the melts and the contents of melt components and gas phase components over the melts were calculated, the temperatures, enthalpies, and entropies of the liquid-gas transition were determined, and the phase diagram of the liquid-liquid + gas-gas transition was obtained.
