Abstract
Thermodynamic modeling of the Ta-V-Si system has been performed. Ground state phase stabilities are reported for all nine binary compounds and for the tau1 ternary intermetallic using an ab initio density functional approach. The calculated energies of formation were included in the thermodynamic modeling based on CALPHAD approach. Thermodynamic remodeling of the sub-systems Ta-V and V-Si and the resulting thermodynamic optimization yielded good agreement with the experimental results in the investigated temperature region 1200 - 1500C.
Abstract (in Czech)
Bylo provedeno termodynamické modelování soustavy Ta-V-Si. Jsou prezentovány fázové stability základních stavů pro všech devět binárních sloučenin a pro ternární intermetalikum tau1, ziskané na podkladě ab initio přístupu. Vypočtené tvorné energie byly zahrnuty do termodynamického modelování prostřednictvím metody CALPHAD. Termodynamické přemodelování podsoustav Ta-V a V-Si a výsledná optimalizace poskytly dobrou shodu s experimentálními výsledky ve zkoumané teplotní oblasti 1200 - 1500C.
