Abstract

Textural evolution in commercial purity aluminum sheet subjected to friction roll surface processing (FRSP) by six combinations of plane/direction and subsequent annealing has been investigated. The characteristic microstructure consisting of fine- and coarse-grained layers in order from the processed surface are formed in the FRSPed and annealed specimens. The shear texture component E {111}⟨110⟩ mainly evolves in the specimen subjected to FRSP and annealing, the fraction of which depends on FRSP plane and direction.
