Preferred orientation formation in sheets worked by continuous cyclic bending
Continuous cyclic bending (CCB) has been recently proposed as a useful straining technique to produce the high strain on the surface and the lower strain in the central layer of the sheet. It was found that preferred orientation is formed by the CCB and subsequent annealing in sheets of an Al-Mg-Mn alloy, a pure aluminum and a commercially pure titanium. For the Al-Mg-Mn alloy sheet, Cube texture in the surface layer is sharpened remarkably during the CCB and the annealing. Further, development of strong cube texture in surface layer is observed in the pure aluminum sheet, with less dimensional change. Transverse direction TD//[0001] is developed after CCB and annealing for the commercially pure titanium sheet worked in rolling direction. Formation mechanism of the preferred orientation by the CCB/annealing process is discussed briefly.
