Popis:	Based on the experimental data available in the literature, the Ag-X (X = B, Fe, Sm, Pu) binary systems were assessed by means of the CALPHAD (CALculation of PHAse Diagrams) approach. Six intermetallic compounds, i.e. αAg2Sm, βAg2Sm, AgSm, Ag51Sm14, Ag51Pu14 and Ag2Pu, were treated as stoichiometric phases. The solution phases including liquid, (Ag, γFe, δPu), (βB), (αFe, δFe, ePu), (αSm, γSm), (βSm), (αPu), (βPu), (γPu) and (δ’Pu) were described by the substitutional solution model with the Redlich–Kister polynomial. A set of self-consistent thermodynamic parameters for each of the binary systems was obtained. The calculated phase diagrams and thermodynamic properties were in agreement with the reported experimental data.
