对纯铜单晶进行了沿(001)和(001)方向的拉伸变形，并对其进行了退火处理，以研究其变形和再结晶行为。在单晶中没有形成大范围的形变带。二次滑移被激活的区域很小，并且随机分布在变形的晶体中。发现相对于初始取向有很大的旋转。退火后，形成了大量的再结晶组织。在(001)单晶中，由于4个滑移面上8个滑移系的激活几乎相等，与变形有关的取向变化很小，完全抑制了大规模的交叉滑移。因此，单晶的加工硬化很大。退火后形成粗大的初生再结晶组织。将上述结果与具有相同拉伸取向的铝单晶的结果进行了比较。
Single crystals of pure copper were tensile-deformed along - and (001) direction and then annealed to study their deformation and recrystallization behaviors. In the single crystals, no large-scale deformation band was formed. The areas where the secondary slip was activated were small and were randomly distributed throughout the deformed crystals. Large rotation with respect to the initial orientation was found. After annealing, many recrystallized grains were formed. In the (001) single crystal, because of almost equal activation of eight slip systems on four slip planes, orientation change associated with deformation was very small, Large-scale cross-slip was completely suppressed. As a result, the work-hardening of the single crystal was very large. After annealing, large primary recrystallized grains were formed. The above results are compared with those of aluminum single crystals having the same tensile orientations.
