Abstract
The effect of grain size on the characteristics of serrated yielding in an Al-Mg-Si alloy has been studied. The critical strain for the onset of serrated yielding was found to be independent of grain size in quenched specimens. With increasing grain size, a transition from the periodic locking form of serrated yielding to irregular serrated yielding was found to occur. The amplitude and strain period of the periodic locking serrations decreased with increasing grain size.Keywords
