Both phenomena are dramatic in dead-weight extensions of annealed specimens of brass or aluminum. The acoustic emission from such specimens was monitored and correlated with the features of the Portevin-Le Chatelier effect. It is shown that, when the discontinuous yielding subsides in aluminum, so does the acoustic emission; in fact, smooth continuous flow can occur in these materials with no detectable acoustic emission. Data are presented which are consistent with the hypothesis that, at room temperature, elastic energy released during a yield increment is proportional to the elastic energy stored since the last yield increment. This is not observed at elevated temperatures.
It is concluded that additional studies of the acoustic-emission phenomena associated with plastic deformation can aid in achieving a better knowledge of the strain-hardening process for crystalline solids..
