Abstract: The phase relationships in the Ti-V-C system were experimentally investigated by means of X-ray, melting point, DTA, and metallographic methods on heat-treated and melted specimens, and a phase from 1400C through the melting range established. The solid state equilibria are characterized by the monocarbide phases, and a limited Ti-exchange in V2C (15 At. % at 1400C); a wide two-phase equilibrium is formed between the carbon-deficient monocarbide solid solution and the metal phase. The V2C-solid solution is terminated by a three-phase equilibrium, V2C + (V,Ti)C1-x + (V,Ti)-ss, in the ternary. Four isothermal reactions occur in the system, of which three correspond to pseudobinary eutectic reactions, and the fourth to a ternary eutectic between metal, subcarbide, and monocarbide. The monocarbide solid solution has a minimum melting point of 2625C at a composition Ti-V-C (6-50-44 At.%).
