Abstract

Serrated yielding in age-hardenable AI-Mg-Si alloys (6xxx series) has been extensively studied by McCormick [1, 2] and by Thomas and Srinivasan [3]. Essentially two types of serrations have been recog- nized: locking and unlocking. Often they are also termed Russell types A and B, respectively [4]. According to Cottrell [5] the excess vacancy concen- tration stimulates diffusion for repeated locking of dislocations resulting in dynamic strain ageing in substitutional solid solution.
