A coincidence model of high-angle grain boundaries can be extended to include deviations from coincidence. The generalised boundary has a terraced structure, corresponding to the densely packed planes in the coincidence lattice, and a superimposed dislocation network, corresponding to a sub-boundary
## Abstract The role of grain boundary misorientation angles on the dislocationโgrain boundary interactions was incorporated into a micro hardening scheme. The current formulation is applicable to both coarseโ and ultrafineโgrained alloys, and evidences the experimentally observed dominant role of
