Abstract : The ternary titanium-tantalum- carbon system was investigated using X-ray, DTA, melting point, and metallographic techniques on chemically analyzed alloys; a complete phase diagram for temperatures above 1500 C was established. The system contains a rather high melting, continuous monocarbide solid solution with a large carbon defect; a moderate titanium-tantalum exchange occurs in both the high and low temperature modifications of the subcarbide, Ta2C. Two four- phase reaction planes are present in the metal-rich portion of the ternary diagram. The results of this investigation are described, discussed, and compared with another partial investigation of this system; possible applications are briefly mentioned. .
