Diffusion and Creep in Niobium Carbide as a Function of Temperature and Carbon Content.
Abstract
The transition metal carbides possess a combination of some of the highest melting points, hardness values and mechanical strengths of any known materials. The contemporary interest in these materials in structural and cladding applications at temperatures where most materials would be molten or would seriously degrade made it imperative that the high temperature diffusion and deformation processes and their relationship to each other be understood. Thus, the principal thrusts of this ARO-sponsored program have been the conduct of self-diffusion studies of 14C and 95Nb in single crystals of NbC0.868 NbC0.834 and NbC0.766 and constant stress compressive creep research on the same materials. Extensive characterization of these materials has also been performed.
