On the sequence of inhomogeneous deformation processes occurring during tensile deformation of strip cast AA5754

Influence of texture and grain structure on strain localisation and formability for AlMgSi alloys

“…Dynamic strain aging characteristically leads to serrated yielding, discontinuous plastic flow and propagating deformation bands and has been observed in many experimental studies for aluminium alloys (e.g. McCormick et al, 1993;An et al, 1996;Wagenhofer et al, 1999;Cheng and Morris, 2000;Shabadi et al, 2004;Clausen et al, 2004;Kang et al, 2005Kang et al, , 2006. The PLC effect is technologically important because it reduces the formability of the material and gives rise to undesired markings on the surface of the shaped product (Kang et al, 2005).…”

Thermomechanical characterization of Portevin–Le Châtelier bands in AlMg3 (AA5754) and modeling based on a modified Estrin–McCormick approach

“…(A detailed review and discussion of these is provided in Section 7 of the current work.) From a technological point of view, the development of PLC bands results in a reduction of surface quality and ductility (Kang et al, 2006;Halim et al, 2007) as well as formability in metal forming processes.…”

Shear Localization and Damage in AA5754 Aluminum Alloy Sheets

“…Gurson and modified Gurson models (Ref 20,21) accounting for mechanisms similar to those in steel have been unable to reproduce experimental data for aluminum alloys. In 5xxx series aluminum alloys, there is experimental evidence that shear bands form prior to damage (Ref [7][8][9]22) or void formation. We use bending tests to clarify the sequence of damage and shear band formation in aluminum.…”
