Abstract

The heights of diffusion barriers for copper-based composite materials with carbon whiskers or fibers are calculated. It is shown that the alloying of the matrix by an additional element, substituting copper in an interstitial Cu-C solid solution, changes the value of the barrier and the migration entropy. This substitutional impurity influences the diffusion of the carbon-copper matrix. Zirconium as the best alloying element for preventing the diffusion of carbon in Cu-C alloy is predicted.
