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.
