The field of transition metal carbides and nitrides is growing rapidly, as additional uses for these interesting materials emerge. Interest in the subject is evidenced by a recent workshop proceedings, a monograph on theory, and several reviews and encyclopedia articles. However, there has been no comprehensive coverage of the topic since the 1970s. 

This volume, which is unique in its coverage, provides a general introduction to the properties and nature of transition metal carbides and nitrides, and covers their latest applications in a wide variety of fields. It is directed at both experts and nonexperts in the fields of materials science, solid-state chemistry, physics, ceramics engineering and catalysis. The first chapter provides an overview, with other chapters covering theory of bonding, structure and composition, catalytic properties, physical properties, new methods of preparation, and spectroscopy and microscopy. 

The summary provided here illustrates the mechanical properties that characterize the transition metal carbides and nitrides. The materials are hard, strong, and somewhat brittle, and resemble ceramic substances. These properties are reviewed by Santhanam (chapter 2), who also describes the commonly used cobalt-binded cermets. 

This section summarized electronic properties of the pure metals and the carbides and nitrides. In all cases the compounds had similar values to the metals. The transition metal carbides and nitrides are therefore interesting... 

Application of transition metal carbides and nitrides in industrial tools... 

Why do carbides and nitrides exhibit the properties that make them so useful in industrial applications It is well accepted that these properties are related to the strength of interatomic bonding.2 In transition metal carbides and nitrides, bonding is believed to have both covalent and ionic contributions.3 The carbon or nitrogen atoms occupy interstitial sites in the metal lattice and are believed to promote strong metal-to-nonmetal and metal-to-metal bonds.1 More detailed bonding explanations require...
