Abstract: This paper investigates acoustic emission under mechanical loading of Pb–Sn alloys. It is revealed that the Kaiser effect under repeated loading is not observed when certain concentrations of constituents lead to establishment of eutectic structures. The absence of acoustic emission memory effect in eutectic Pb alloys is explained. The proposed explanation is based on peculiar features of plastic flow caused by the motion of eutectic alpha- and beta-phase colonies at the joint interfaces.

Keywords: acoustic emission, Kaiser effect, eutectic alloys.
