Thermodynamic Description of the Gadolinium-Cadmium Phase Diagram

20241 citationOpen accessUniversité Ibn Zohr

Abstract

The thermodynamic optimization of the Gd-Cd binary system was carried out with the help of CALPHAD (CALculation of PHAse Diagram) method., GdCd3, Gd13Cd58 and GdCd8 have been treated as stoichiometric compounds while a solution model has been used for the description of the liquid, HCP_A3 (αGd), BCC_A2 (βGd) and HCP_A3 (Cd) phases. The intermetallic compounds GdCd,α-GdCd2, β-GdCd2, Gd11Cd45 and GdCd6, which have homogeneity ranges, were treated by a two-sublattice model. The calculations based on the thermodynamic modeling are in a good agreement with the phase diagram data and experimental thermodynamic values.
