Experimental results on the plateau behavior in the cyclic stress-strain curve of single crystals that were located on different sides of the stereographic triangle were summarized. Contrary to the case of single-slip oriented crystals, the crystallographic orientation had a marked effect upon the plateau behavior in the cyclic stress-strain curves of double-slip and multiple-slip oriented crystals. The presence or absence of a plateau in the cyclic stress-strain curves, as well as the corresponding plateau stress amplitude, depended not only upon the modes and intensities of dislocation interactions among the slip systems operating in the crystals, but also upon the slip deformation characteristics that were associated with crystal orientations. The plateau region in the cyclic stress-strain curve disappeared only when multiple slip played a governing role during cyclic deformation.
