摘要：

Deformation behaviour and acoustic emission (AE) of an Al-10.5wt.%Zn alloy with different grain size and different precipitation structure have been studied. The serrated flow activity and the AE activity exhibit an indistinct dependence on the grain size. The serrated flow activity rather decreases but the AE activity increases with increasing volume fraction of coherent precipitates.
