Acoustic emission voltage versus strain curve showed a peak near yield point where the plastic deformation started. After showing the peak, the acoustic emission voltage reduced gradually with increment in the plastic strain. Fluctuations in the acoustic emission voltage also emerged after about 1.5% plastic strain. Both the value of acoustic emission peak voltage and the amplitude of fluctuations in the acoustic emission voltage became higher as the average grain size increased. The acoustic emission signals generated under the tensile deformation were mostly burst-type ones. Moreover, on the surface of deformed specimen, a lot of deformation twins were observed. Therefore, it was assumed that the burst-type signals resulted mainly from the formation of deformation twins.
