The through thickness texture gradient in accumulative roll bonding (ARB) processed materials is largely
dependent on the friction between the rolls and the sheet during deformation. In this study, AA6061 aluminum
alloy was pre-heated to 200 C for 180 s and subjected to ARB deformation under dry conditions
for up to 5 cycles using rolls with a high surface roughness. The imposition of high friction conditions during
rolling resulted in a large texture gradient in the through thickness of the ARB strip. The bulk texture
at the strip surface mainly comprised the Rotated Cube orientation for all cycles. The strip quarter thickness
consisted of a combination of a Copper dominated b-fiber and the Rotated Cube orientation after 5
cycles. The bulk texture at the strip center evolved from a predominantly Cube orientation in the fully
annealed condition to one that comprised typical fcc rolling orientation components after 1 cycle. Thereafter,
a gradual increase in the volume fraction of the Rotated Cube component was seen for up to 5
cycles. As expected, the average bulk texture up to 5 cycles returned the highest volume fraction for
the Rotated Cube orientation along with significantly smaller volume fractions for the ideal rolling orientations.
The combination of high friction induced shear deformation and the unique alternating sandwich-
type deformation pattern of ARB resulted in an increasingly uniform redistribution of shear-type
orientation components across the strip thickness with increasing number of cycles.
