Defect states in substoichiometric tantalum carbide
Physical Review B, 1986X-ray photoelectron spectroscopy was used to determine core-level binding energies (BE's) and valence-band structure for ${\mathrm{TaC}}_{\mathrm{x}}$ over the range 0.5\ensuremath{\lesssim}x\ensuremath{\lesssim}1.0. As x decreased from about 1.0 to about 0.5, the tantalum 4d and 4f BE's shifted toward the Fermi level by about 0.8 eV and the p-d ...

Epitaxial Growth of Tantalum Carbide
Japanese Journal of Applied Physics, 1972Films of tantalum carbide (TaC) known as a material with high melting point (3877°C) are formed on substrates by electron beam evaporation technique. The substrates are CaF2, MgO and NaCl single crystals cleaved in air. The range of substrate temperature is from 25°C to 1030°C.

Growth of tantalum carbide monocrystals
Journal of Crystal Growth, 1981Abstract TaC monocrystals have been grown from a Co flux using intermittent stirring and a modified Czochralski technique. The crystals contain no inclusions according to Debye-Scherrer diagrams. They show sharp Laue spots. The eutectic temperature of the system Ta-Co has been found to be at 1270°C.

Sintering kinetics of tantalum carbide
Soviet Powder Metallurgy and Metal Ceramics, 1982Tantalum carbide sinters at a temperature above 2500‡C. Decreasing the powder particle size activates the sintering process, but even with a powder of 0.17-Μm particle size specimens sintered at 2700‡C have a porosity of 11%. Coarse powders (> 7–8 Μm) sinter, without densification, at 2000–2200‡C by a surface self-diffusion mechanism. Fine powders (

Oxidation of tantalum carbide alloys
Soviet Powder Metallurgy and Metal Ceramics, 19761. A study was made of the oxidation of hot-pressed specimens of tantalum carbide, alloys of tantalum carbide with 5, 10, and 15% Ni and 10% (Ni, W), and VK8 alloy in air at temperatures of 500, 600, and 700°C. 2. It was established that in the temperature range investigated tantalum carbide and its alloys are superior in oxidation ...

Gas evolution from zirconium carbide, niobium carbide, and tantalum carbide powders
Soviet Powder Metallurgy and Metal Ceramics, 1986This work was undertaken with the aim of determining the gas contents of zirconium carbide, niobium carbide, and tantalum carbide powders as functions of their processing history. A high-vacuum, high-temperature apparatus was used, connected to an oilless evacuation system and instruments for the mass-spectrometric measurement of amounts and ...

Elastic properties of tantalum carbide (TaC)
Solid State Communications, 2005Abstract Elastic properties of TaC have been investigated experimentally and by model calculations. The elastic stiffness coefficients c11=597(11) GPa and c44=153(2) GPa were determined on a (100)-oriented disc-shaped monocrystal at room temperature using a plane-wave ultrasound method.

Spark plasma sintering of tantalum carbide
Scripta Materialia, 2010A tantalum carbide powder was consolidated by spark plasma sintering. The specimens were processed under various temperature and pressure conditions and characterized in terms of relative density, grain size, rupture strength and hardness. The results are compared to hot pressing conducted under similar settings.
