Ex-perimental results show that the cyclic deformation behavior of three types of ' copper bicrystals with grain boundaries parallel to loading axis is similar to that of a copper single crystal oriented for single slip, and the cyclic stress-strain (CSS) curves all contain a plateau. But the platcau stresses of the bicrystals are higher than the typical value 28 MPa off a single slip copper single crystal and are different from each other. While, for a bicrystals containing a grain boundary perpendicular to loading axis and two component crystals one one which is oriented for single slip and another is oriented for double slip, there is no plateau in the CSS curve, and it was found that the CSS quite is quite similar to that of copper polycrystals. Ob-servation of surface morphology shows that the above cyclic deformation behavior of the four types of bicrystals is closely related to the occurrence of double slip or multiple slip due to the constraint of grain boundary and the different degrees of dislocation interaction between the operative slip systems.
