In the present paper, the complete ternary B–Fe–Ti system is thermodynamically modelled based on our own experimental results and information reported in literature. Series of key experiments were performed for the binary Fe-B, Fe-Ti and the ternary B-Fe-Ti systems in order to obtain parameters of invariant reactions. For this, 19 alloys were prepared and analysed in the as-cast and annealed conditions by means of SEM/EDS, SEM/EBSD, XRD and DTA/DSC techniques. A new ternary boride Ti 2 FeB 2 with the crystal structure of Mo 2 FeB 2 (an ordered derivative of U 3 Si 2 crystal structure type) was revealed to exist at temperatures from 1273 K to solidus. The elaborated thermodynamic description was applied to calculate selected phase equilibria as to provide a comparison between calculated and experimental results. The calculations are shown to reproduce available experimental data entirely well. Image 1 • Investigations of 19 alloys by SEM, XRD and DTA/DSC techniques. • Discovering of new ternary Ti 2 FeB 2 boride. • Thermodynamic modelling of the entire B-Fe-Ti system. • Comparison of calculated and experimental results.
