Thermodynamic assessment of Cr-Nb-C and Mn-Nb-C systems

▸ Enthalpies of formation for hypothetical Nb carbides were studied by ab intio methods. ▸ Parameters for the liquid phase in the Cr-C binary system were reoptimized. ▸ Assessments for Cr-Nb-C and Mn-Nb-C systems were made for the first time.
