Abstract
Computer simulation of grain boundary diffusion in aluminium bicrystal s during one- and two-step annealing has been carried out. Different s tructures of grain boundaries are considered. The results are represen ted in form of iso-concentration contours and compared to the models o f Fisher, Le Claire, Sozouka and Whipple. The diffusion coefficient of copper is determined from the shape of the diffusion wedge of copper in the grain boundary.
