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 FeC and MnC are presented together with those of the most important transition metal carbonitride systems TiCN and ZrCN. 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.
