On the relation between sliding and migration of symmetrical tilt grain boundaries
We demonstrate that, based on their unique geometry, the migration of all symmetrical and certain asymmetrical tilt grain boundaries is necessarily accompanied by sliding parallel to the interface. By contrast, for all other types of grain boundaries no crystallographic necessity exists for migration to be coupled with sliding. Except in the case of the coherent (111) twin boundary in the fcc lattice, the coherently-twinned translational configuration is identified as the saddle-point configuration for the migration of the symmetrical tilt boundaries.
