Abstract

Acoustic emission upon mechanical loading of alloys of the Pb–Sn system is studied. It is revealed that the Kaiser effect is not observed under repeated loading of the material at component concentrations leading to the formation of a eutectic structure. An explanation for the absence of acoustic-emission memory in eutectic lead-based alloys is proposed. The explanation is based on the specific character of the plastic flow implemented due to the motion of eutectic α- and β-phase colonies as a whole along common interfaces.

Pb-Sn系统共晶合金加载下的Kaiser效应违反

摘要

研究了Pb-Sn系统合金在机械载荷下的声发射。揭示了在组分浓度下反复加载材料导致形成共晶结构的情况下未观察到Kaiser效应。提出了共晶铅基合金中不存在声发射记忆的解释。解释是基于由于共晶α相和β相菌落整体沿共同界面运动而实现的塑性流动的特定特征。
