Abstract
The influence of phase composition on the manifestations of the Portevin–Le Chatelier effect was studied in Al-Mg alloys using the digital image correlation technique. The smooth deformation curves were observed for Al-3Mg and Al-4.57Mg-0.35Mn-0.2Sc-0.09Zr alloys, whereas type A serration can be distinguished on the deformation curve of Al-5.4Mg-0.52Mn-0.1Zr alloy. At the same time, both the smooth plastic deformation and the stress serration are related to the propagation of a deformation band. The band velocity and the band passed distance for investigated alloys were estimated.
