The Gd-Pd system was critically assessed using the CALPHAD technique. The s
olution phases (liquid, bcc, fee and hcp) were modeled with the Redlich-Kis
ter equation. The intermetallic compounds GdPd and GdPd,, which have a homo
geneity range, are treated as the phases GdM and MPd3, respectively, by a t
wo-sublattice model with Gd in GdM and Pd in MPd3 on one sublattice and M o
n the other, where M is used as an abbreviation for a mixture of Gd and Pd.
The other phases were treated as stoichiometric compounds. A set of self-c
onsistent thermodynamic parameters of the Gd-Pd system was obtained. (C) 20
