摘要
The analysis of mechanism and kinetics of the diffusional zinc penetration along the moving grain boundary during diffusion induced grain boundary migration (DIGM) has been performed in aluminium samples deposited with zinc. The anisotropy of a new Zn-enriched grain emerging during DIGM has been observed. This anisotropy results from both the change of migration distances and Zn-content in the new grain with regard to the plane of original grain boundary. The zinc profiles within DIGM zone have been discussed based on Hillert's criterion. It has been shown that the shape of zinc profiles is modified by the increasing contribution of the volume diffusion, especially at the higher annealing temperatures.
