Results are analyzed for an experimental study of phase equilibria within the volume of ternary systems Si–C–Me d, where Me d is W, Ta, Mo, Nb, Hf, and V. Information is summarized for the structure of SiC–Me dSi2 sections, and it is noted that all of them are quasibinary and are classified as a eutectic type. Correlation is established between eutectic temperatures in SiC–Me dSi2 systems, and also between Me dSi2 concentration within eutectic and Me dSi2 melting temperature. Equations are suggested describing this correlation.
