采用晶体刻蚀法，在铜中暴露111个平面，以确定重冷轧铜中立方体取向微带周围邻近子结构的取向。在将其表征为取向群后，将其与轻度退火材料中未发育的立方体取向微带邻近区进行比较，其中几乎所有发育良好的再结晶晶粒都是立方体取向的。通过检查两组取向邻域，证明了只有被具有θ度取向关系的材料包围的立方体微带才能提供立方体核[111]。因此，立方体结构源于原子核在各种取向环境中的竞争，成功的原子核具有它们最初生长的环境，其特征为θ度[111]关系。该过程最好描述为微生长选择，其中局部织构决定了核的生存能力和竞争优势，而全局变形织构（即由传统衍射方法确定的织构）是这些核消耗的织构，随着再结晶的进行，有可能进一步生长选择。
A crystallographic etch in which 111 planes are exposed in copper has been used to determine the orientation of the neighbouring substructures surrounding cube oriented microbands in heavily cold rolled copper. These, after characterisation into orientation groups, were compared with the neighbourhoods of undeveloped cube oriented microbands in lightly annealed material in which almost all well developed recrystallised grains were of cube orientation. By inspection of the two sets of orientation neighbourhoods it is demonstrated that only cube microbands surrounded by material with a theta-degrees [111] orientation relationship provide cube nuclei. Thus the cube texture arises from competition between nuclei in a variety of orientation environments, the successful nuclei having environments into which they initially grow characterised by a theta-degrees [111] relationship. The process is best described as micro-growth selection, in which the local texture determines the viability and competitive advantage of nuclei, while the global deformation texture (i.e. that determined by traditional diffraction methods) is that which is consumed by those nuclei, with the possibility of further growth selection as recrystallisation proceeds.
