摘要：

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.
