Dynamic properties of grain boundaries (GBs), as reviewed in the present report, include diffusion along stationary and migrating boundaries, various boundary diffusion-controlled solid-state processes and mechanism of GB migration. Applicability of different GB diffusivity measurement techniques, influence of diffusion direction and misorientation angle on diffusivity and extent of agreement between experimental results and theoretical computations have been discussed. Relevant features of discontinuous type of transformations pertaining to GB migration and diffusion have been highlighted. Diffusion data for stationary and migrating boundaries in Ni-In system are presented for a suitable comparison. Finally, a new mechanism has been proposed for the migration of GBs on the basis of some recent experimental results.
