چکیده انگلیسی
In the present work, the Ta-B system was thermodynamically optimized based on the CALPHAD method using data of liquidus temperatures, invariant transformations and enthalpy of formation from the literature as well as new experiments performed in our group. The phases Ta3B2, TaB(rt), Ta5B6, Ta3B4 were modeled as stoichiometric compounds. On the other hand, L (liquid), BCC, Ta2B, TaB(ht) and TaB2 were modeled as solution phases using the Compound Energy Formalism (CEF), with excess terms described by the Redlich-Kister polynomials. (βB) was treated as a pure element without any Ta solubility. The present thermodynamic modeling is in good agreement with the experimental data.
