In this study, we investigate the deformation bands (DBs), viz. DBI and DBII, and cell bands (CBs) in the near--multiple-slip-oriented single crystals during cyclic deformation. Three different types each of DBIs [, , and ] and DBIIs [, , and ] can be summarized as the primarily activated slip plane and the combination of activated primary and coplanar slip systems, respectively. The formation planes of CBs [, , and ] are perpendicular to the cross-slip plane and parallel to the primary slip direction. The highly symmetrical characteristics of multiple-slip-oriented single crystals can produce inconsistent correspondences between DBs and CBs.

循环变形近1~11取向铜单晶变形带及晶胞结构分析
在这项研究中,我们研究了变形带 (DB),即。DBI 和 DBII,以及近-循环变形过程中的多重滑移取向单晶。三种不同类型的 DBI [, , 和 ] 和 DBII [, , 和 ] 可以分别概括为主要激活的滑动平面和激活的主要和共面滑动系统的组合。CBs的形成平面[, , 和 ] 垂直于交叉滑移平面并平行于主滑移方向。多滑移取向单晶的高度对称特性会在 DB 和 CB 之间产生不一致的对应关系。
