Abstract
The experimental thermochemical and phase diagram data for the Co-Mo system were assessed. A consistent thermodynamic description, using a Redlich-Kister model for the solution phases and sublattice and line compound models for the intermetallics, was obtained and agrees well with the critically evaluated experimental data from the literature. Several variations of the sublattice model for the ς and phases were compared with the traditional models used for these phases in other systems. Inclusion of the magnetic contribution to the Gibbs energy expressions of the Co-based solid solutions produced an abrupt decrease of the terminal Mo solubility in the fcc (Co) phase with decreasing temperature consistent with measured data. The magnetic contribution to the thermodynamic properties also suggested the formation of a fcc (Co) miscibility gap, and a high temperature stability region of the paramagnetic hcp (Co) phase.Citation
