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. Uranium 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 tie-triangles, which have one side coincident with either the U-Pu or the Pu-C binary side and have the opposite apex touching 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.Isothermal sections at reactions are outlined. Uranium monocarbide forms a complete series of solid solutions with plutonium monocarbide.
