The U- Pu- C ternary phase diagram for the composition range from 0 to 50 at.% carbon and for temperatures below 835 deg C was constructed from metallographic, x-ray diffraction, and melting range data. Isothermal sections at reactions are outlined. Uranlum monocarbide forms a complete series of solid solutions with plutonium monocarbide. All phase boundaries other than those of the monocarbide phase represent the sides of three-phase tietriangles, which have one side coincident with either the U-- Pu or the Pu-C binary side and have the opposite apex touchlng the phase boundary of the monocarbide solid solution, (U, Pu)C. The metal: carbon stoichiometry of the monocarbide is influenced by the U: Pu ratio. (auth)
