The role of grain boundary misorientation angles on the dislocation–grain boundary interactions was incorporated into a micro hardening scheme. The current formulation is applicable to both coarse- and ultrafine-grained alloys, and evidences the experimentally observed dominant role of the misorientation angles on the deformation response of the latter.
