dc.description.abstractThe effect of grain size on the damping capacity of a dilute Zn-0.3Al alloy was investigated. It was found that there was a critical strain value (?1 × 10 ?4 ) below and above which damping of Zn-0.3Al showed dynamic and static/dynamic hysteresis behavior, respectively. In the dynamic hysteresis region, damping resulted from viscous sliding of phase/grain boundaries, and decreasing grain size increased the damping capacity. While the quenched sample with 100 to 250 µm grain size showed very limited damping capacity with a loss factor tan? of less than 0.007, decreasing grain size down to 2 µm by equal channel angular pressing (ECAP) increased tan? to 0.100 in this region. Dynamic recrystallization due to microplasticity at the sample surface was proposed as the damping mechanism for the first time in the region where the alloy showed the combined aspects of dynamic and static hysteresis damping. In this region, tan? increased with increasing strain amplitude, and ECAPed sample showed a tan? value of 0.256 at a strain amplitude of 2 × 10 ?3 , the highest recorded so far in the damping capacity-related studies on ZA alloys. © 2017, The Minerals, Metals & Materials Society and ASM International.en_US
