A high number of dislocations have been observed in an as-cast high-damping Mg-3Cu-1Mn-2Zn-1Y(wt.%) alloy using transmission electron microscope (TEM). The majority of dislocations are distributed in parallel and uniform rows. Mg2Cu particles in the matrix are often found to be associated with a number of parallel dislocations. Twins containing stacking faults are also frequently observed. The formation of eutectic phases occurring during casting is followed by precipitation of secondary intermetallic phases in supersaturated α-Mg with alloying elements upon annealing. The observed defect structures provide useful experimental evidence supporting the previously proposed damping mechanism for Mg alloys.
