Abstract
The Portevin-Le Chatelier (PLC) effect has been investigated by deforming Al–2.5%Mg alloy in the strain rate regime where simultaneously two types (type B and type A) of serrations appear in the stress–strain curve. Our analysis of the time series data suggests that in this strain rate regime the entire PLC dynamics is governed by a single band which changes its character during the deformation.
