✦ Synopsis

The phase diagram of the ternary Ti-B-C system has been constructed from 300 to 3500 K, especially for the sections TiC y -TiB 2 and B 4 C y -TiB 2 . The calculation of the energy parameters describing the phase equilibria with the participation of TiB 2 has been carried out in the subregular solutions approximation. The presence of wide homogeneity regions of carbides, TiC 0.47 -TiC 1.0 and B 4 C 0.45 -B 4 C 1.0 , has been taken into account. Ordering in nonstoichiometric titanium carbide TiC y at a temperature below 950 K has been calculated by the order parameters functional method.
