Abstract
Deformation behaviour and acoustic emission (AE) of an Al-10.5%Zn alloy with different precipitation structure have been studied. The serrated flow activity decreases but the AE activity increases with increasing volume fraction of coherent precipitates. These results seem to contradict a recent model published by Brechet and Estrin.

Key words
deformation behaviour, acoustic emission (AE), Portevin-Le Chatelier effect, Al-Zn alloy
