-The effect of grain boundary regions on the total amount diffused during an exchange experiment has been numerically modeled. The total amount diffused increases when the grain size is decreased, and when the ratio of the grain boundary and lattice diffusion coefficients increases. Grain boundary migration increases the total amount diffused during part of the processing time. The numerical ca...
