The need for improved materials in high temperature structural applications has stimulated research into the mechanical behavior of a number of materials including the refractory hard metals. The transition metal carbides are of particular interest for a number of reasons, for example a these compounds include the materials having the highest melting points, b they are extremely strong, and c they deform plastically in a manner similar to fcc metals. The purpose of this paper is to review the present understanding - or lack of it - of the deformation process and the factors affecting the mechanical behavior of these technologically important materials. Consequently, the more interpretable information obtained in recent years from studies of single crystals, rather than that from sintered polycrystalline materials, is emphasized.
