Zusammenfassung:[Display omitted] •Activated slip systems affect the formation of deformation bands and cell bands.•A three-dimensional reconstruction of deformation band and cell band is built.•Three types of deformation bands and cell bands are summarized.•There is an inconsistent correspondence between deformation bands and cell bands. In this study, we investigate the deformation bands (DBs), viz. DBI and DBII, and cell bands (CBs) in the near-1¯11-multiple-slip-oriented single crystals during cyclic deformation. Three different types each of DBIs [(111), (1¯1¯1), and (1¯11¯)] and DBIIs [(2¯11), (1¯21), and (1¯12)] 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 [(121), (1¯1¯2), and (2¯11¯)] 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.
