In order to study the effect of tantalum on the structure and properties of the complex carbides (Ti, W, Ta) C, the authors prepared solid solutions (Ti, W, Ta) C with the molar concentration ration TiC: WC = 64:36 (35:65 by weight). It is shown that the electrical resistivity of the alloys decreases with increasing amount of tantalum carbide, i.e ...

Isothermal oxidation of dense HIPed tantalum carbide materials TaC and Ta2C, has been performed in flowing oxygen between 750 and 850 °C. The behaviour of the two carbides: i.e. TaC (NaCl type structure) and Ta2C (hexagonal type), is characterized by the growth of a non-protective oxide scale which, on square section samples, forms a maltese cross ...

Analyzing Tantalum Carbide (TaC) and Hafnium Carbide (HfC) for Spacecraft Material
2021Spacecraft needs thermal protection systems material that rise more than ±1.260 °C on nose cap and wing leading edge. It depends on the heat loading encountered during the re-entry of the orbiter into the atmosphere. Recently, the spacecraft uses thermal protection system (TPS) materials like reinforced carbon-carbon (RCC), High-Temperature Reusable ...

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.

Resonant two-photon ionization spectroscopy of jet-cooled tantalum carbide, TaC
The Journal of Chemical Physics, 2010The optical spectrum of diatomic TaC has been investigated for the first time, with transitions recorded in the range from 17 850 to 20 000 cm−1. Six bands were rotationally resolved and analyzed to obtain ground and excited state parameters, including band origins, upper and lower state rotational constants and bond lengths, Fermi contact parameter bF

Study And Characterization of A Metal Matrix Composite Reinforced with Tantalum Carbide-TaC
International Journal of Material Science, 2015Steel is an alloy EUROFER promising for use in nuclear reactors, or in applications where the material is subjected to temperatures up to 550°C due to their lower creep resistance under. One way to increase this property, so that the steel work at higher temperatures it is necessary to prevent sliding of its grain boundaries.

This work is devoted to a study of the influence of tantalum on the structure and properties of three-phase alloys. The investigations were made with a constant weight ratio of Ti:WC = 35:65% and an unchanged carbon content. The alloys were prepared by mixing of the (T, W, Ta)C carbides with cobalt and tungsten carbide. The pressed specimens were given
