In the present work, an update of experimental knowledge and the thermodynamic description of the ternary B-Fe-V system was done with a focus on the V2FeB2 ternary phase. For this purpose, several alloys containing the ternary phase were prepared and were investigated after long-term annealing at 600 and 1080 degrees C by the methods of scanning electron microscopy, x-ray diffraction, and differential thermal analysis. The obtained results and knowledge about the ternary phase were used to improve the description of the boron-iron-vanadium ternary system. A new model for the ternary phase was used. The thermodynamic parameters for the VB, V3B4, and Fe2B borides were also modified. The calculation performed using the new thermodynamic database achieved a very good agreement with the experimental results.
