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