Mechanism of the plastic deformation of the AZ31 alloy upon low-cycle reverse bending

The development of texture upon deformation by reverse bending of sheets of the AZ31 alloy has been studied. The deformation was represented as the alternation of tension and compression of the layers remote from the middle of the sheet. The mechanisms of plastic deformation that are responsible for the formation of texture at different stages of deformation are proposed on the basis of the data of X-ray diffraction analysis of the texture and substructure and metallographic data.
