摘要	Cyclic stress-strain curves (CSSCs) of some copper bicrystals with a grain boundary (GB) perpendicular to the stress axis were compared. It was found that the component crystal orientations played a decisive effect on the CSSCs of these bicrystals. The CSSC of [(5) over bar 913]perpendicular to[(5) over bar 79] copper bicrystal with two single slip oriented component crystals exhibited two plateau regions in the lower and higher plastic strain range, respectively. For [(1) over bar 23]perpendicular to[(3) over bar 35] and [(3) over bar 45]perpendicular to[(1) over bar 17] copper bicrystals, both with one single slip and one double slip oriented component crystals, the corresponding CSSCs only displayed one plateau region or pseudo-plateau region in the low and intermediate plastic strain range, respectively. However, the [(1) over bar 34]perpendicular to[(1) over bar 34] copper bicrystal with the same single-slip-oriented component crystal showed one plateau region over a wide plastic strain range in its CSSC, which was somewhat similar to the result for copper single crystal oriented for single-slip. In this paper, the effect of the component crystal orientations on the CSSCs of these copper bicrystals is discussed. (C) 1998 Elsevier Science S.A. All rights reserved.
