Texture evolution in aluminum sheet subjected to friction roll surface processing and subsequent annealing

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.
