Thermodynamic remodeling of the Co-Ga system Academic Article

abstract

• The thermodynamic properties and phase relations of the Co-Ga binary system are remodeled based on the CALPHAD approach. In this work, Co-Ga() is considered to be non-stoichiometric and Co-Ga3 to be stoichiometric. The phase is thermodynamically described by a two-sublattice model (Co,Ga)0.5 (Co,V a)0.5. The stability of the phase is restricted in the low-temperature regions by giving necessary driving force constraints. The lattice parameters and enthalpy of formation of the and Co-Ga3 phases have been compared with first-principles calculations based on density functional theory. The calculated Co-Ga phase diagram is compared to previously calculated ones. 2010 Elsevier Ltd. All rights reserved.
