Diffusion of carbon in the carbides of niobium
Description
The reaction between niobium and graphite over the temperature range 1700°∼2200°C has been investigated. The reaction products were found to be Nb2C and NbC which formed between the graphite and the metal. Parabolic growth behavior was observed for both phases. The rate constants for layer growth can be expressed as(This article is not displayable. Please see full text pdf.) The diffusion coefficients of carbon in Nb2C and NbC was estimated to be(This article is not displayable. Please see full text pdf.) assuming that D is independent of concentration.
