Abstract
Acoustic emission (AE) characteristics have been studied during the thermoelastic martensitic transformation of Cu-Zn-Al alloy. The average energy measurements of acoustic emission events qualitatively exhibit the same behaviour as the acoustic emission measurements done by the ring-down count rate: the AE event mean energy is more important during the reverse transformation than during the direct one; the mean energy of the events is higher for the transformation of the first plates of martensite than for the following plates. For the reverse transformation the mean event energy is higher for the same plates which are the last to disappear.Keywords
