Thermodynamic analysis of the Co–W system.

Density functional theory (DFT) calculations including spin polarization were performed to obtain the energies for all end-member configurations of the μ phase, which were used to evaluate the Gibbs energies of the μ phase. The Co–W system was thermodynamically re-assessed in the present work. The present calculated phase diagram fits well with the experimental data. Applying the DFT results was essential for giving a better description of the μ phase. [ABSTRACT FROM AUTHOR]
