Effects of Zn content (0–1.5, in wt.%) on damping capacities of the as-homogenised and the hot-rolled Al–9.2Mg alloys are investigated. The Zn addition plays a significant role in the strain-amplitude-dependent damping (Qh−1). As for the as-homogenised state, Qh−1 decreases at first and then increases with the higher Zn content, and the Al–9.2Mg–1.5Zn alloy exhibits the highest Qh−1 (>0.016). As for the hot-rolled state, Qh−1 is just the reverse and the Al–9.2Mg–0.5Zn alloy exhibits the highest Qh−1 (>0.018). The damping behaviours are in accord with the G–L dislocation theory, which are determined by stacking fault energy (SFE), textures and precipitates.

锌含量对铝镁合金阻尼行为的影响

研究了锌含量(0-1.5%,以重量%计)对均质和热轧Al-9.2Mg合金的阻尼能力的影响。锌的添加在取决于应变幅度的阻尼(Q h -1)中起重要作用。至于非均质状态,Q h -1首先降低,然后随着锌含量的增加而增加,而Al–9.2Mg–1.5Zn合金表现出最高的Q h -1(> 0.016)。至于热轧状态,Q h -1正好相反,而Al–9.2Mg–0.5Zn合金表现出最高的Q h -1(> 0.018)。阻尼行为是与符合G-L位错理论,这是由堆积断层能量 (SFE),织构和析出物确定的。
