The Nd–C binary system has been assessed based on the experimental investigation, thermodynamic calculations and the literature survey. The intermediate compounds Nd2C3 and βNdC2 (high-temperature form of NdC2 phase) were considered to be the non-stoichiometric phases whereas the αNdC2 (low-temperature form of NdC2 phase) was treated as the stoichiometric phase. Contents of carbon in the Nd–Csat samples in Nd–Nd2C3 range were measured in the present study. The phase diagram of Nd–C system and enthalpies of formation of Nd2C3 and NdC2 carbides have been modeled using the FactSage software.
