The results show that, to the inclined grain boundary bicrystal with single slip components, the cyclic stress strain curve (CSSC) ealsts a plateau or quasi-plateau region, while the CSSC of tricrystal shows no plateau.Observation of surface morphologies indicated that owing to the strain incompatibility of three grains, at lower strain amplitude the triple junction retards obviously the primary slip in grains and makes deformation near it smaller than that near bicrystal junction. The eastness of crack initiation at the same triple junction is closely related to loading direction.
