Abstract
The solid state and solid-liquid equilibria of the Nb-Ta-C system was determined by melting point determinations, X-ray and chemical analysis, metallography, and differential thermal analysis for temperatures above 1500C. The ternary system has a complete solid solution of monocarbides and also of subcarbides if the differences in carbon atom ordering is disregarded. Eutectic troughs in both the metal-rich and carbon-rich regions of the ternary are present. Calculated tie-line distributions agree well with experimental results.
