Abstract
Extensive researches have been done on deformation and recrystallization of single crystals. One main reason is that complicated intergranular interactions can be avoided during deformation of single crystals and hence single crystals are very suitable for fundamental researches. However, it is also due to this major difference, the results obtained from single crystals are not directly applicable to polycrystalline materials. In this paper, the influence of external constraint on the deformation behavior of copper single crystals with {l_brace}110{r_brace} orientations was investigated by embedding them into metal frames of different strengths. Hence, the deformation environments of the embedded single crystals are in between those of unconstrained single crystals and crystals in ordinary polycrystalline aggregates. Thus, the present work should help to bridge the gap between the present understandings on the deformation of single crystals and polycrystalline samples.
