“…The results obtained by Brenton [56] and Jun [70] are very similar despite the difference in the chemical composition, which seems to confirm the earlier observation that the carbon content does not affect the Young modulus value. On the other hand, the results obtained by Speck [66] are lower than the results obtained by Brenton [56] and Jun [70], probably due to a higher porosity level in the specimen. According to Brenton [56], the relationship between temperature and the Young modulus can be described by the equation:…”

“…For this reason, the mechanical properties of these materials are usually measured by ultrasonic methods with sintered or isostatically-pressed specimens [66]. In these tests, the Young modulus, E, and shear modulus, G, are calculated from measured longitudinal and transversal sound speeds in the materials, and other properties, like Poisson coefficient, ν, and bulk modulus, B, are calculated from these.…”

“…The advantage of this combination of fabrication route and ultrasonic testing is that these tests require specimens with a simple geometry that can be easily obtained by sintering. However, the results will depend strongly on the porosity level attained, and reliable results require test specimens with porosity levels below 5% or 6% [66]. There is also the possibility of using monocrystals for these measurements [67], but this is not a very common method given the difficulties in producing crystals of materials with high melting points from the liquid state.…”

“…Speck [66], Brenton [56] and Jun [70] studied the variation of the Young modulus with temperature, and their results are shown in Figure 12. The increase in temperature causes a decrease in the Young modulus for all chemical compositions.…”

Transition metal carbides are interesting materials with a singular combination of properties, such as high melting points, high hardness, good transport properties and relatively low costs, which makes them excellent candidates for several technological applications. The possible applications of NbC carbide remained unexplored as it was in the past expensive and available in limited volumes. In order to guide investigations of the applicability of NbC, a deeper understanding of the physical properties of this carbide is fundamental. In this review paper, key physical properties of NbC are compiled with emphasis on its chemical bonding, a careful description of the C-Nb phase diagram, the phases formed and the crystal structures. Thermal properties are discussed and correlated with the intrinsic and extrinsic features of NbC. Finally, elastic properties are discussed.

This study measured the Vickers hardness of the sintered refractory carbides B 4 C, Mo 2 C, NbC, TiC, V 8 C 7 , W 2 C, WC, WC-SiC, and ZrC over a wide range of test forces between 0.49 and 196 N. The results showed an indentation size effect (ISE), with hardness values that increased with decreasing test force for the carbides. The test force dependence of the hardness was analyzed by the proportional specimen resistance (PSR) model. The value of the a 1 term that reflects the elastic resistance in the model was obtained for the carbides and compared with their measured elastic, shear, and bulk moduli. It was not clear what type of modulus related strongly to the a 1 term. There was a strict correlation between the hardness at an infinite test force and at a test force of 9.8 N. However, the hardness at a test force of 0.49 N a little poorly reflected the hardness at an infinite test force.

Basic properties and use of transition metal carbides and carbonitrides are presented in this article. Starting from crystal chemistry, bonding, and preparation, the article also briefly discusses analytical chemistry of chemical and physical carbon analysis as well as thermodynamics. Updated versions of phase diagrams of group 4, 5, and 6 transition metals with carbon as well as phase diagrams of FeC and MnC are presented together with those of the most important transition metal carbonitride systems TiCN and ZrCN. A large part is devoted to the solid‐state properties because they make carbides and carbonitrides interesting materials for application. The presentation of these properties includes hardness, thermal properties, conductivities, carbon diffusivity, and elastic properties. Some ternary and quaternary carbonitrides are also discussed. Several of these properties are given as a function of temperature and composition. Examples for application of carbides in modern hardmetal types such as recent development in fine‐grained hardmetals and functional gradient hardmetals are included. The topic is closely connected to the article Nitrides: Transition Metal Solid State Chemistry.
