AbstractThe cyclic deformation behavior of [001] isoaxial copper tricrystals as well as bicrystals and single crystals was studied. It was found that the cyclic hardening curves of tricrystals, bicrystals and single crystals did almost overlap at the initial rapid hardening period. The difference between them was not obvious even at the saturation period. Cyclic stress-strain (CSS) curves of bicrystals were higher than that of single crystals. The CSS curve of tricrystals was located between them. There were no effect zones in the vicinity of grain boundaries and triple junctions according to the observation of dislocation microstructures. The strengthening effects of grain boundaries and triple junction lines on axial stress of specimens were almost negligible owing to the formation of Lomer-Cottrell locks caused by the reaction of dislocations on different slip planes.
