A critical assessment and thermodynamic calculation of the boron-carbon-titanium [B-C-Ti] ternary system

The B-C-Ti system has been critically assessed and calculated in the temperature region of 1400 degrees C up to the melting range employing the Thermocalc program system, The liquid phase is described using a substitutional model, The ternary solid solubility of boron in titanium carbide has been taken into account by using a two-sublattice model (Ti)(1)(B,C,Va)(1). The calculated isotherms and isopleths are presented and compared with the experimental information, The B-C-Ti reaction scheme is presented including the Ti3B4 phase.
