Abstract Scope |
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. In order to validate calculated results, eleven different alloys in the compositional range of 10 to 40 at. % B 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 observations. Differential thermal analysis of selected alloys was applied to investigate the occurring phase transformation during heating/cooling. In our further work, Si will be added to the present thermodynamic database V-Ti-B envisaging the development of the quaternary dataset V-Ti-Si-B and their alloys. |
