Randomization of cube texture formed in 6061 aluminum alloy was attempted by applying the wavy roll-forming method. Rolls having a wavy-shaped surface with waves which were about 8 mm in wavelength and 3 mm in amplitude were used for wavy roll-forming. Specimens were heated at 623 K and then roll-formed, followed by reheating at the same temperature and roll-formed again. This process was repeated 4 or 15 times, then the specimen was flattened using conventional flat rolls. The roll-formed specimens were annealed and then cold-rolled at room temperature and finally annealed at 773 K for 1.8 ks. Textures formed in the specimens were analyzed by electron backscattered diffraction measurements. The relative intensity of cube orientation was reduced by the annealing before the cold-rolling. The low intensity was maintained after the final annealing.
