Tantalum Carbide is the refractory ceramic\nmaterial because of its both high temperature behavior and mechanic characteristics. In this review, researches\nare encountered in literature are discussed such as crystal structure, Ta/C phase diagram, Ta/C compound ratio\nbased mechanic characteristics ...
Tantalum is a rare transition metal having a density of 16.6 g/cm3and a melting point of 3017° C. Tantalum is hard, highly corrosion resistant, and is widely used as an alloying material, for example in making high strength alloyed steels or super alloys or carbide reinforced tools. The ...
With allowance for ordering of 0953-8984/8/43/020/img1, the phase diagram of the Ta - C system has been calculated and constructed. The effects of non-stoichiometry and ordering on the period of a base B1-type lattice of tantalum carbide and on the superconducting critical temperature have...
The phase equilibria in the systems Nb-Cr-C and Ta-Cr-C at 1050 and 1000°C were also determined. The ternary carbide Nb 3 Cr 3 C was not detected.doi:10.1007/BF00774153T. F. FedorovA. A. Baikov Institute of Metallurgy, I. Franko Lvov State University, USSRN. M. Popova...
phase diagramssteelThe carbide layers which were formed in the bond interface of an explosively welded tantalum–steel composite after heat treatment between 1053 and 1273 K were examined metallographically and analyzed using an electron microprobe technique. Two layers of carbides, TaC and Ta 2C, ...
An x-ray microanalysis shows that this layer conta~ms tantalum and carbon and the gold tinge of the layer permits the assumption that it consists of tantalum monocarbide. The thin layers (to 2-3 Dm) have the characteristic micromorphology...

but also influenced by the hard carbide such as tantalum carbide (TaC) and tungsten carbide (WC) that generated on the surface of the alloy. The surface hardness of the Ta-W alloy is far higher than that of the core region under the combined strengthening mechanism of Ta-W solid solution...
