Abstract

Optimized descriptions of the phase diagram and thermodynamic properties of the Pr–Al system have been obtained from experimental thermodynamic and phase diagram data by means of the computer program THERMOCALC based on the least squares method, using models for the Gibbs energy of individual phases. The system contains six intermetallic compounds. The calculated standard enthalpies of formation of Pr3Al, Pr2Al, PrAl, PrAl2, PrAL3, Pr3Al11 are: –25.4, –33.5, –44.0, –54.9, –47.5, and –42.3 kJ/mol, respectively. A consistent set of thermodynamic parameters was derived. Optimized and experimental data are in good agreement.

Keywords: Pr–Al system; Phase diagram; Thermodynamic assessment; Enthalpy of formation
