Abstract
Lüders band and Portevin–LeChatelier (PLC) band propagation in polycrystalline Cu–0.15at.%Al has been studied by multiple zone laser scanning extensometry during tensile deformation. The dependence of the propagation rate on the external deformation rate is investigated in a wide range (ε̇=6.67×10−6–1.3×10−2 s−1) at selected temperatures (100–300 °C), in particular for the PLC bands of type B which propagate in a jerky manner. The local strain rates within the bands are determined and the results are compared with recent theoretical modelling of PLC band propagation.
