Description
The phase diagram and thermodynamic data of the Co-Ce system have been critically assessed by means of the computer programs THERMO-CALC. Special attention is paid to the Co5Ce and Co17Ce2 compounds. The Co5Ce and Co17Ce2 compounds are described as stoichiometric compounds in the first treatment; in the second treatment, they are described as one phase denoted δ, and a three-sublattice model Co15Ce2(Ce,Co2), based on the crystal structure, is used to model the δ phase. The other phases are modelled with the Redlich-Kister formula [liquid, fcc, bcc, hcp] or as stoichiometric compounds [Co19Ce5, Co7Ce2, Co3Ce, Co2Ce, Co11Ce24]. Good agreement is obtained between the calculations and experimental results. (orig.)
