Thus it can be concluded that in the better damping capacity magnesium alloys, there are two mechanisms operating, disloion damping and twinning damping. The effect of grain size on the damping capacity and strength of a high damping alloy (Mg-l%Mn) and a low damping alloy (Mg-l%Mn-0. 5%A1- 0.2%Zn) was also investigated.
