The "C" Factor in LeClaire's Theory of Solute Impurity Diffusion

Abstract:

Article Preview

The "C" factor for the calculation of the relative activation energy for solute impurity diffusion using LeClaire's theory as modified by Burachynsky and Cahoon has been determined for the diffusion of several solutes in FCC Cu , FCC Fe and BCC Fe. Inclusion of the "C" factor results in good agreement between the calculated and experimental values of relative activation energy for impurity diffusion inn the solvents considered. For positive values of relative valence, Z, the value of C is given by C » 20 Z. For negative values of Z, C » 0.
