A calculation of the variation with concentration of the diffusivity of carbon in austenite is given. Absolute rate theory is used to calculate the intrinsic jumping frequency of C-atoms located in differing atomic configurations in the austenite lattice. The relative concentrations of configuration
The application of the converging-diverging pore model, previously developed for the simulation of structural effects on the diffusion of nonadsorbed gases in porous media, to surface transport is described. Good agreement with experimental results reported for surface diffusion of propane and neope
