Thermodynamic modelling is an effective approach to accelerate the development of novel materials such as V-based alloys. In the present work, the results of the thermodynamic modelling of the ternary system V-Ti-B using the “CALculation of PHAse Diagrams” (CALPHAD) method are presented. The thermodynamic description of the binary systems V-Ti, V-B and Ti-B is based on available literature whereas thermodynamic parameters for the ternary system stem from the iterative approximation to experimental data, which further serve for verifying the calculated phase diagram. Therefore, eleven different alloys in the compositional range of 10 to 40 at. % V and Ti were analysed aiming at identifying the appearing phases and their crystal structures. A set of thermodynamic parameters is proposed for the isothermal phase diagram at 1400°C which exhibits a very high agreement with experimental observation. In our further work, the thermodynamic data will be useful to develop the quaternary system V-Ti-Si-B.
