The Pd-Tb system was critically assessed by means of the CALPHAD technique.
The liquid and solid solution phases were modeled with the Redlich-Kister
equation. The intermetallic compounds PdTb and Pd3Tb, which have a homogene
ity range, were treated as the formulae (Pd, Tb)Tb and Pds(Pd, Tb), respect
ively. The other intermetallics were treated as stoichiometric compounds. A
set of self-consistent thermodynamic parameters of the Pd-Tb system was ob
tained.
