TERNARY PHASE EQUILIBRIA IN TRANSITION METAL-BORON-CARBON-SILICON SYSTEMS. PART 1. RELATED BINARY SYSTEMS. VOLUME 5. TA-C SYSTEM. PARTIAL INVESTIGATION IN THE SYSTEMS NB-C AND V-C

Abstract

The alloy system tantalum-carbon was investigated by means of X-ray, DTA, and melting point techniques on heat-treated and chemically analyzed alloys; a complete phase diagram was established. Analogously to the findings in the Ta-C systems, a previously unknown phase reaction of the Nb2C phase was found to occur at high temperatures. The melting temperatures of the monocarbide phase and the NbC-C eutectic reaction isotherm were redetermined. The alpha- beta-Me2C-phase reaction could not be found in the vanadium-carbon system.
