The Ternary System Tantalum-Hafnium-Carbon at 2050 degrees C

Abstract

"An isothermal cross section of the tantalum-hafnium-carbon (Ta-Hf-C) system at 2050 C was constructed from x-ray diffraction, chemical analysis, metallographic, and microhardness data. No phases other than those appearing in the three binary systems were observed in the ternary system. A liquid phase was found in a large portion of the hafnium-rich corner of the ternary section.
