Title: Texture evolution of an Fe–Ni alloy sheet produced by cross accumulative roll bonding

The texture evolution in an Fe–36%Ni (wt.%) alloy, severely deformed to a true strain of 4.8 by cross accumulative roll bonding, was investigated using X-ray diffraction and a visco-plastic self-consistent simulation. At the surface, the C component ((100)<011>) exhibited a strong continuous strengthening from cycles 1 to 5. At the mid-thickness region, the texture evolution appeared to be cyclic due to the cyclic nature of the imposed deformation. A copper-type texture was observed even after cycles, whereas a new major texture component named H ((012)<22{sup ¯}1>) was formed after odd cycles, with several other minor ones belonging to a (210) fiber. A significant change in the plastic anisotropy was introduced by cross accumulative roll bonding processing. - Highlight: • The texture after CARB is characterized by a typical C shear component near the surface. • The texture evolution in the mid thickness of samples seen to be cyclic • VPSC model reproduced the experimental texture in the early CARB cycle. • The CARB process can reduce the plastic anisotropy of the sheet.
