BONDING, STRUCTURE AND MECHANICAL BEHAVIOR OF VANADIUM CARBIDE 9SINGLE CRYSTALS.

Abstract

An approximate band structure for VC has been derived. From this, it is concluded that the bonding in VC arises primarily from interactions between orbitals on the metal atoms, and that this component of the bonding is stronger in VC than in TiC. Measurements of the compressive yield strength of VC0.85 single crystals over the range 900 -1800C support this conclusion. However, a domain structure, associated with ordered carbon vacancies, has been observed in these crystals. The anisotropy introduced by such ordering may also contribute to the higher strength of this material. (Author)
